Adds fiat currency metadata to payments

Browse source 
Adds fiat currency information to payment invoices and ledger entries.

This allows for tracking the fiat value of transactions and provides a more complete financial picture. Calculates the fiat amount proportionally based on the user's balance and includes the fiat currency, amount, and exchange rates in the invoice's extra data. This data is then extracted and added to the ledger entry's metadata when recording the payment.
