📝 Problem Statement

BankWirePaymentDetails lacked support for account_identity and account_balance objects, needed to pass account holder identity information and real-time balance data (via providers like Plaid, MX, etc.) on bank transfer/ACH orders.

📝 Solution Overview

Added two new optional fields to BankWirePaymentDetails:

• accountIdentity — holds names, addresses, phone numbers and emails associated with the payment account
• accountBalance — holds available balance, service provider, timestamp and currency code

New files:

• AccountIdentity.java — model with 4 optional fields (names, addresses, phoneNumbers, emails)
• AccountBalance.java — model with 4 required fields (availableBalance, serviceName, updatedAt, currencyCode)
• AccountBalanceServiceName.java — enum for the serviceName field (PLAID, MX, STRIPE, TRUELAYER, KLARNA, VISA, MASTERCARD, YODLEE)

Modified:

• BankWirePaymentDetails.java — added accountIdentity and accountBalance fields
