Adds lightning payment option for settling receivables

Browse source 
Implements the ability for users to settle their outstanding balance
using a Lightning Network invoice.

Generates an invoice on the Castle wallet and polls for payment,
automatically recording the transaction once payment is detected.

The UI is updated to display the invoice and handle the payment process.
