feat: send denominationId in deposit payload + block submit on denomination mismatch

- All 4 deposit forms (Current/Savings/FD/RD) now send denominationId +
  denominationValue in denominationBreakdown so the backend can persist rows.
- Submit is disabled when a denomination breakdown is entered but its total
  does not match the transaction amount.
