Subject: [PATCH] feat: cleanup types and add missing request fields (#2346)

- Add `ledger_hash` and `ledger_index` to `account_nfts`,
`nft_buy_offers`, and `nft_sell_offers` requests.
- Add `nft_page` to `ledger_entry` request.
- Create `LookupByLedgerRequest` to clean up `ledger_hash` and
`ledger_index` which are optional on most request objects.

Closes #2135
