Added enhancement to nFront to fall back to 'transaction_currency' and 'transaction_amount' when 'billing_currency' and 'cardholder_billing_amount' are missing,
so that the app always shows the correct currency and amount even for reversal advice messages where billing fields are not present.
Added enhancement to Virtual Card PAN Generation.
Implemented backend support for Areeba Payment Gateway (ARPG), including new source channel handling, Transfers API updates, CMS-level integration, and forex logic.
Enhanced the PIN retry counter (now it is set to 5 attempts).
Several internal enhancements have been implemented, which do not significantly impact the current implementation for clients.
