fix(accounts): savepoint per-row bank entry in Bank Transaction upload (Postgres)

create_bank_entries loops rows inserting+submitting a Bank Transaction; on failure the except calls bank_transaction.log_error (INSERT) with no rollback, raising InFailedSqlTransaction on Postgres, and the next row runs in the poisoned txn. Savepoint per row + rollback(save_point=) before log_error. No-op on MariaDB.
