[Tazapay] Add AED support (#23189)

## Reason

Added support for the United Arab Emirates Dirham (AED) as a new currency option in our payment system to expand our service offerings in the Middle East region.

## Overview

- Added AED to the `CurrencyUnit` and `FiatCurrencyUnit` enums across all GraphQL schemas
- Created a new `TazapayAedAccountIntegration` class to handle AED-specific banking operations
- Implemented IBAN validation and BIC code extraction for AED bank accounts
- Added support for creating AED bank destinations in the Tazapay client

## Test Plan

- Verified AED IBAN validation logic works correctly with test IBANs from UAE banks
- Confirmed the new currency appears correctly in all relevant GraphQL schemas
- Tested the integration with Tazapay's API for AED transactions
- Ensured proper BIC code extraction from UAE IBANs
