## Summary
Adds live ETL indexing for mptoken_issuance_history by extracting MPT
issuance references from transaction metadata and transaction fields,
then writing both MPT transaction index shapes during the existing MPT
ETL pass. Successful transactions are indexed from affected MPT ledger
objects; failed transactions are indexed only when they carry an
attached MPT issuance reference.
## Changes
- Adds `getMPTokenIssuanceTxsFromTx` to extract issuance transaction
index records from `tesSUCCESS` transactions.
- Scans `AffectedNodes` generically for `MPToken` and `MPTokenIssuance`
ledger objects instead of relying on a transaction-type allowlist.
- Reconstructs issuance IDs for `MPTokenIssuance` objects with
`makeMptID(sequence, issuer)`, avoiding the hashed ledger-key trap.
- Deduplicates distinct issuances per transaction and attaches the
transaction’s affected accounts for account-level fanout.
- Extends `MPTExt` so live and initial ETL data writes:
- existing MPT holder index data
- `mptoken_issuance_transactions`
- `account_mptoken_issuance_transactions`
- Adds a Prometheus counter for MPT issuance transaction index rows
written by ETL.
- Logs unexpectedly large per-transaction fanout.
## Tests
Adds unit coverage for:
- failed transactions producing no records
- `MPTokenIssuanceCreate`, `Destroy`, `Set`, and `MPTokenAuthorize`
- generic transaction-type coverage through `Payment`, `Clawback`,
`OfferCreate`, and `AMMDeposit`
- ID reconstruction from issuance nodes
- multi-issuance fanout and deduplication
- affected-account propagation
- ETL extension writes to both backend index paths while preserving
existing holder indexing

Why
This is the first PR in the broader `mptoken_issuance_history` plan. It
lands the additive schema/backend layer first so later PRs can safely
add live ETL indexing, historical backfill, and finally the RPC handler
gated on backfill completion. Keeping this step dark avoids exposing
partial history while still making the stack reviewable in small pieces.
Summary
Adds the storage and backend primitives for MPT transaction-history
filtering.
- Adds Cassandra tables:
- mpt_transactions
- account_mpt_transactions
- Adds MPTTransactionsData and backend interface methods for
writing/fetching both MPT index shapes.
Implements Cassandra write/fetch paths with forward/reverse pagination,
raw-page cursor behavior, and case-insensitive tx_type filtering before
transaction hydration.
- Adds MockBackend coverage for the new pure-virtual methods.
- Adds Cassandra integration tests for round-trip behavior, ordering,
pagination, missing transaction blobs, sparse tx_type filtering, account
fanout, and account-side filtering.
- Stop accepting connections during graceful shutdown in the old web server
- Stop all the services before Clio exits
- Move cache saving into stop callback
