fix: resolve PostgreSQL type mismatches and add willexecutor debug logging

- Fix get_next_address_index: use try_get::<i32> for PG SERIAL/INTEGER columns
- Fix search_tx: use try_get::<i32> for PG status column
- Fix execute_insert: parse locktime (String→i64) and in_vout (String→i32)
  before binding to PG INTEGER columns
- Fix execute_insert: bind tbl_out vout as i32, amount as String for PG
- Fix save_new_address: cast xpub i64 to i32 for PG INTEGER column
- Fix get_pending_txs: cast i64 bind params to i32, use try_get::<i32> for reads
- Fix get_stats: use try_get::<i32> for all numeric PG INTEGER columns
- Add trace logging in parse_request_transactions for xpub address matching
- Add trace logging in get_all_addresses_by_xpub for query debugging
