fix(accounts): savepoint per-row merge in Ledger Merge (Postgres)

Browse Source 
start_merge merges accounts in a loop; on failure it only rolled back when not in_test, so in tests a failed merge_account left the Postgres txn poisoned and the except log_error + the finally db_set(status) raised InFailedSqlTransaction. Wrap each row in savepoint('ledger_merge_row') and rollback to it unconditionally before log_error - this recovers the txn in both paths without the full rollback discarding the rest of the test transaction. Production still commits per successful merge, so the per-iteration savepoint rollback is equivalent to the prior full rollback. No-op on MariaDB.
