refactor: Move decreaseOwnerCount onto AccountRootEntry

Replace the entry-taking decreaseOwnerCount free function with a
writable member of AccountRootEntry, and drop the temporary friend
declaration from the previous change. The member uses the entry's view
and journal, so call sites pass their journal to the entry constructor.
The AccountID-based overload stays as a shim.

-### Breaking changes
-
-- The `ripplerpc` request field, which selects the shape of the JSON-RPC reply envelope, is now validated, and a value that is not exactly `"1.0"`, `"2.0"` or `"3.0"` is rejected. Two things it does not reach: a WebSocket session, which reads the field only to echo it back, and API version 3, where the field selects nothing and so is neither read nor checked, `ripplerpc: "banana"` and no `ripplerpc` at all being served alike. A request sending `"2"`, `" 2.0"`, `"2.00"`, `"02.0"`, `"2.0.0"`, `"10.0"` or any other text, such as `"abc"` or `"x2"`, gets a working reply today. After this ships, such a request sent alone gets HTTP 400 with `ripplerpc is not a supported version`, charged as a malformed request, and such an entry of a `"method": "batch"` body gets that error in its own reply while the batch answers 200. A client that spells the version loosely must therefore be corrected to one of the three exact values, or omit the field. Previously the value was compared as a string, which both accepted values that name no version and ordered multi-digit versions incorrectly: `"abc"` and `"x2"` sorted above `"3.0"` and so selected version 3, and `"10.0"` sorted below `"2.0"` and so selected version 1. Requests that send one of the three supported values, or omit the field, are unaffected.
-- `subscribe`: every subscription a connection holds must name the same `api_version`. The first `subscribe` establishes it, and a later one naming a different version is refused with `apiVersionConflict`, registering nothing; the message names the version the connection's subscriptions are served at. The HTTP status is 400 where the envelope derives it from the error, with `ripplerpc: "3.0"` or at API version 3, and 200 with `ripplerpc` `"1.0"` or `"2.0"`, as for every error; a WebSocket frame carries no status. A `subscribe` refused for another reason, a stream name the server does not have for one, still fixes that version, since the registrations it makes are spread through the handler. A connection that subscribed one stream at `api_version` 2 and another at 1, in two calls, was previously served both at version 1, the later call's, so the first stream's shape changed under it. The version is fixed for the connection's life: a client that wants another version opens another connection. On the webhook path the subscriber is keyed on its `url` alone, so the refusal reaches a second admin because of a first admin's version, and the message names the version the url's subscriptions are served at, and no remedy: releasing a url means unsubscribing its streams, which would remove that first admin's subscription, and the server cannot tell the two callers apart. Naming the url alone does not release it, a subscriber a stream map still holds not being evicted. This reaches every API version, since version 1 and version 2 content is not interchangeable either: version 2 renames `transaction` to `tx_json` and hoists `hash`, so a version 1 client handed version 2 content finds no `transaction` member.
-- `batch`: An entry of a `"method": "batch"` request that names `api_version` both inside `params` and at its own top level is now served at the version inside `params`. It was previously served at the top-level version whenever the one inside `params` resolved to version 1, so an entry asking for version 1 explicitly and something else at the top level changes which version answers it. A lone request can name both values too, and for it the version inside `params` has always won; reversing that precedence was confined to a batch entry.
-- `batch`: every entry of one batch request is now served at the same API version. An entry may name the version the body names, or name none and inherit it, and a body whose entries name two different versions is refused whole with `Batch entries name different versions` at HTTP 400, charged as a malformed request. **This is visible to a version 1 or 2 client:** a `"method": "batch"` body could mix versions across its entries, each entry being dispatched at its own, and the difference is observable because the reply shape changes with the version. Three bodies change. One whose entries name two different versions is now refused instead of answered. One where some entries name a version and others name none now serves all of them at the named version, where an entry naming none was served at version 1; the same applies to a version named on the request's own top level, which the entries now inherit. One whose top level names a version and whose entries name a different one is now refused, where the top-level value was ignored and each entry was served at the version it named. A body whose top level names no version or the same version as its entries, and whose entries agree with one another or name none at all, is unaffected. A `"method": "batch"` body naming at its own top level a version the server does not serve is refused with `invalid_API_version` at HTTP 400, where it was previously served at version 1 as if it had named none. No test pinned the mixing behavior and the line that produced it was a fallback about where the field sits rather than a decision that entries may differ, so this is a correction rather than a removal of a feature: a per-entry version made the entry cap above unanswerable, since a cap can only ask about a body that has one version.

-- A JSON-RPC (HTTP) request may send its parameters as an object, `"params": {"account": "r..."}`, as well as the array of one object that was already accepted. This reaches every API version: such a request was previously rejected with HTTP 400 and `params unparsable`, and is now served. A request that already sends the array form is unaffected. An entry of a `"method": "batch"` request that carries a by-name `params` object is read for `api_version` and credentials from that object. Previously such an entry had its `api_version` read from its top level and its credentials ignored, since credentials were read only from an array-form `params`.
-- A JSON-RPC (HTTP) request may name its `api_version` at its own top level, beside `method` and `id`, as well as inside `params`. The member is an XRPL extension, which the JSON-RPC 2.0 specification does not define; placing it beside the specification's own members is what lets a version 3 client send a specification-shaped request. This is honored from API version 3 up, so it needs `[beta_rpc_api]`; a version below that named at the top level is ignored, exactly as it always has been. Previously only an entry of a `"method": "batch"` request had its own top level read; a WebSocket request, which is one flat object, has always been read there.

-### Bugfixes
-
-- A request echoed back in an error reply now has every credential-bearing field masked: `admin_password`, `admin_user`, `passphrase`, `password`, `secret`, `seed`, `seed_hex`, `url_password`, `url_username` and `username`. Nesting no longer matters, so a credential inside `params` is masked too. The same masking is applied to every request and reply written to the log, and it covers six further names that only a reply carries: `master_key`, `master_seed`, `master_seed_hex`, `validation_key`, `validation_private_key` and `validation_seed`, which is how `wallet_propose` and `validation_create` used to write a live private key to the log. A request or reply written to the log is truncated at 10,000 characters. An `[rpc_startup]` line that does not parse is reported by its position in the section and the parser's message, never by its text, and no command runs for it.
-- The command line client no longer prints a credential the operator did not type. A failing command echoes the request it built under `request_sent`, which carries the `admin_password` the client copies out of `[port_rpc]` in the config, so `./xrpld account_info rBogus` printed that password to stdout and into any captured output. `request_sent` is now masked. The `rpc` member beside it, which echoes the arguments as they were typed, is unchanged. The command line client also no longer writes an unparsed `json` or `ripple_path_find` argument to its trace log before parsing it, where a `secret` inside that argument could not be masked; it logs the parsed request instead, masked. The reply it receives is logged the same way, parsed and masked, where the raw body was written before, a `validation_create` answer included.
-- A WebSocket frame that does not parse, or exceeds the request size limit, is answered `{"type": "error", "error": "jsonInvalid", "size": <bytes>}`. The frame's body is reported by size rather than echoed back in a `value` member, since a body that does not parse has no fields to mask. A client that read `value` gets `size` instead.
-- Four error codes that named no HTTP status of their own, and so answered 200 on a reply reporting an error, now name one: `actMalformed`, `alreadyMultisig` and `alreadySingleSig` answer 400, and `actNotFound` answers 404. **Only API version 3 reports these four.** A request sending `ripplerpc: "3.0"` at API version 1 or 2 still receives 200 for all four, as it always has, so `account_info` on a malformed account or one the ledger does not hold answers 200 for those clients exactly as before.
-- `submit`, `simulate`, `transaction_entry`, `ledger_entry` and `ledger_accept`: Errors from these methods now include `error_code` and `error_message` alongside the `error` token, as every other method already did. Each error now answers the status its code names: 400 for a malformed request, 404 for `transactionNotFound`, 500 for an internal failure, and 501 for `notYetImplemented` and `notStandAlone`. That status change reaches only a request sending `ripplerpc: "3.0"`, or API version 3, which are the envelopes that derive the status from the error. With `ripplerpc` `"1.0"` the status stays 200 and the two new members appear beside `error`; with `"2.0"` the status stays 200, `error_code` appears, and the `code` and `message` members carry the code and the message rather than null, since that envelope copies them from `error_code` and `error_message` and drops `error_message`. From API version 3 the twenty-one `malformed*` tokens `ledger_entry` names each report the code they own instead of 31.
-- A reply reporting HTTP 402 or 502 now carries a status line. Those two statuses named no case in the switch that writes one, so such a reply began with a header instead and did not parse as an HTTP response at all. Both are reachable at any API version with `ripplerpc: "3.0"`, which derives the status from the error code: 402 through `highFee` from `sign`, `sign_for` or `submit` with a low `fee_mult_max`, and 502 through `dbDeserialization` from `tx`. The eleven statuses that already named a case report the same phrase they always have.
-- An error reply to a request sending `ripplerpc: "2.0"` or `"3.0"` no longer carries a stray `"error_message": null` beside the error it reports. The member appeared only when the `Server` log partition was set to debug or lower, because the log statement read `error_message` after the reply had renamed it to `message`, and reading it put it back as null. So the reply a client received depended on the server's log level, and the log line itself printed an empty message. Both are fixed.
-- A body the server rejects before it reads a request out of it now says what was wrong. A body over the size limit answers `Request is too large`, and a body that parses to `{}` or `null` answers `Request is empty`; both previously answered `Unable to parse request: ` with nothing after the colon, the parser having recorded no error for them. Any other body that is not an array does not parse, which includes one that is only whitespace and one whose top-level value is a string, number or boolean; it answers `Unable to parse request: ` followed by the parser's own reason, as it did before. The status is 400 for all three, as before, and this reaches every API version. A top-level array, the one other body nothing can read a request from, is answered with a JSON error object instead, which the entry on top-level arrays below describes.
-- `batch`: An entry that is not identified through a secure gateway no longer clears the connection's `X-User` and forwarded-for values for the entries after it, so every entry of one body reports the role and username it would have reported on its own.
-- `batch`: Every entry of a `"method": "batch"` request is now charged against the sender's resource allowance, including one rejected before it reaches a handler, and the request stops at the first entry the connection is too loaded to serve. A reply array can therefore be shorter than the request array, and its last element depends on where the batch stopped. An entry that is not a JSON object, or names an API version the server does not serve, is charged before its role is known and answered with its own rejection; if that charge took the connection over the drop threshold, the batch stops there and that rejection is the last answer. Every other entry met over the threshold is answered `Server is overloaded` and nothing follows. A client should read any reply array shorter than its request as a connection over the drop threshold, whatever the last element says. A well-behaved client is unaffected; one that sends thousands of entries in a single body no longer gets every one of them answered.
-- A body the server rejects before it reads a request out of it is now charged against the sender's resource allowance, as a malformed request already was. Ten conditions were free: a body over the size limit, one that does not parse, one carrying no document, one that is neither a JSON object nor an array, a `"method": "batch"` naming no entry array, and six ways a top-level array is not a batch this server can serve. The answer to the first five is unchanged; an array's answer changes as the entry on top-level arrays below describes, the one generic rejection it received having become six. A well-behaved client is unaffected; one that repeats such a body exhausts its allowance and is refused the next request a handler would have served. A WebSocket frame that does not parse, or exceeds the request size limit, is charged the same way, and a connection that sends only such frames is closed once it crosses the drop threshold.
-- `subscribe`, `path_find`: A subscription is now served at the API version its own `subscribe` call named, rather than at the version of the most recent `subscribe` or `path_find` on the same connection. A `path_find` no longer changes the version anything that connection has subscribed is served at. An ordinary request is unaffected: it names its own version and is answered at it, so a connection subscribed at `api_version` 3 still calls `account_info` at version 1 and reads the version 1 shape.
-- `batch`: A batch request served at API version 3 or above is now refused when it holds more than 100 entries, before any entry is dispatched. The cap reads the one version the body is served at, so no ordering of the entries evades it. A body served below version 3 is unaffected and stays bounded only by the request size limit.
-- A top-level JSON array, which is the JSON-RPC 2.0 batch form accepted from API version 3, is now rejected with a JSON-RPC error object rather than a plain text body when it cannot be served: when it is empty, holds more than 100 entries, holds nothing that could be a request, names no API version of 3 or above that the server serves, or names two different versions the server serves. An array naming no served version of 3 or above is refused for requiring version 3, or, where every version it names is one the server does not serve, with `invalid_API_version`. One entry naming a version the server does not serve does not reject an array in which another entry names a served version: it is answered on its own, inside the reply array, with the same `-32606` code. This reaches every API version, since no earlier version accepts an array at all: a client that sent one received HTTP 400 with `Unable to parse request: ` and now receives the same status with a JSON body. The message also names the version rather than the shape where the version is what is wrong, which is what a client with `[beta_rpc_api]` disabled receives.

 ## XRP Ledger server version 3.5.0
 
 Version 3.5.0 is not yet released.
 
 ### Additions in 3.5.0
 
-- `subscribe`, `unsubscribe`: Added an optional `mpt_issuances` request field, an array of MPT issuance IDs (hex strings). Subscribers receive the same `transaction` message as the `transactions` stream for each validated transaction whose metadata affects a subscribed issuance. MPT issuance subscriptions count toward the per-connection subscription limit. An empty array, a non-array value, or an invalid ID returns `invalidParams`. ([#5671](https://github.com/XRPLF/rippled/pull/5671))
-- `ledger_entry`: Add full support for checks, NFT offers, payment channels, and signer lists. ([#6319](https://github.com/XRPLF/rippled/pull/6319))

@@ -93,7 +50,6 @@ Version 3.4.0 is not yet released. These changes are available in the 3.4.0 beta
 - `account_lines`: The `peer` field now returns an error if the value is not a string. [#7728](https://github.com/XRPLF/rippled/pull/7728)
 - `ledger`: `delivered_amount` is now included in the metadata of successful `AccountDelete` transactions when transactions are expanded (`expand`, or admin-only `full`). Previously it was only added for `Payment` and `CheckCash`, which made `ledger` inconsistent with `tx` and `account_tx`. [#5706](https://github.com/XRPLF/rippled/pull/5706)
 - `noripple_check`: The `transactions` field is no longer included in error responses; it is still returned (possibly as an empty array) whenever `transactions` is `true` and the request succeeds. A malformed `account` is now rejected before the ledger is looked up, so that error response no longer carries the `ledger_hash`, `ledger_index`, and `validated` fields ([#6303](https://github.com/XRPLF/rippled/pull/6303)).
-- `transaction_entry`: An object or an array in `tx_hash` now returns `malformedRequest`, like any other value that is not a hex hash, instead of an `internal` error.

 CI runs it over the build output and the Conan cache, and again in the upload job
 before anything is published. You can run it yourself:
 
 ```bash
-bin/nix/check-nix-store-refs.sh build
-bin/nix/check-nix-store-refs.sh ~/.conan2-nix

+bin/check-nix-store-refs.sh ~/.conan2-nix
 ```
 
 It works on Linux too, but asserts something narrower there: the toolchain always
-writes the store into `PT_INTERP` and `RUNPATH`. That is fine for the pinned
-glibc, whose path does not move, but not for the GCC runtime, which moves with
-every GCC update. So [`conan/profiles/default`](../../conan/profiles/default)
-links build-context packages, whose executables run during the build, with
-`-static-libstdc++ -static-libgcc -Wl,--as-needed`, and
-[`conan/profiles/sanitizers`](../../conan/profiles/sanitizers) does not
-instrument them. CI checks that they load nothing from the store but glibc, from
-the graph `conan install --format=json` writes:
+writes the store into `PT_INTERP` and `RUNPATH`, and CI builds inside an image
+whose store is fixed for its lifetime, so that is fine. Only the binaries
