Bring in BYTEA type definitions, indexer changes, GraphQL schema/resolver
updates, processor changes, and test files from opxdr-bytea-2 branch.
These files had no modifications on the timescale branch.

Change hash, account_id, operation_xdr, and address columns from TEXT
to BYTEA type while preserving all TimescaleDB hypertable configuration,
composite primary keys, and chunk settings.

… statechanges)

Convert hash, account_id, operation_xdr, and address columns from TEXT
to BYTEA in BatchInsert, BatchCopy, and query methods. Uses HashBytea,
AddressBytea, and pgtypeBytesFromNullAddressBytea for type conversions.
Preserves TimescaleDB junction table patterns (ledger_created_at columns,
composite primary keys, parameter numbering).

Adopt BYTEA types (HashBytea, AddressBytea, XDRBytea, NullAddressBytea)
in test data while preserving TimescaleDB-specific patterns:
- Keep ledger_created_at in junction table INSERTs
- Use generic "duplicate key value violates unique constraint" assertions
  (TimescaleDB chunk-based constraint names differ from standard PG)
- Keep 5-value return from processLedgersInBatch (includes startTime/endTime)

Rename inner err to addrErr in address BYTEA conversion loops to avoid
shadowing the outer err variable from pgx.CopyFrom.

Add *TimeRange parameter to transactions, operations, and state changes
BatchGetByAccountAddress. Inserts ledger_created_at >= / <= conditions
inside the MATERIALIZED CTE (transactions/operations) or after the
account_id WHERE clause (state changes) for early chunk pruning.

Add buildTimeRange helper that validates since <= until and constructs
a *data.TimeRange. All three account field resolvers (Transactions,
Operations, StateChanges) now build and pass time range to the data layer.

Update GetAccountTransactions, GetAccountOperations, and
GetAccountStateChanges client methods with since/until *time.Time
parameters. Update corresponding GraphQL query builders to declare
$since: Time, $until: Time variables and pass them through.
Fix integration test call sites for updated signatures.

Add appendTimeRangeConditions unit tests covering nil, since-only,
until-only, both, and table-qualified column cases. Add resolver
tests for Transactions, Operations, and StateChanges with time range
params: since in past/future, until before since validation error,
and combined with pagination/filters. Update existing resolver tests
for new since/until method signatures. Fix BatchGetByToID test calls
that had extra nil argument.

Resolve 5 conflicts by accepting timescale changes:
- Add bloom filter sparse indexes to transactions, operations, state_changes
- token_id column as BYTEA (from tokenid-bytea rebase)
- Add account_category composite index for state_changes
- Enable timescaledb.enable_sparse_index_bloom in docker-compose and test containers

Combines query optimizations (composite cursors, MATERIALIZED CTEs,
time range since/until, decomposed cursor conditions) with account
registration removal from remove-filtering.

Cosmetic changes from gqlgen: import reordering and type
declaration formatting.

query-optimize simplified state change account resolution to use
AccountID directly from the row, making this method and its type
obsolete. Also includes gofumpt formatting fixes.
