Invoice payment failures now return a card_error when a charge is declinedBreaking changes

What’s new

Updates invoice payment attempts to return a card_error when the charge is declined. This aligns /v1/invoices/{INVOICE_ID}/pay with /v1/charges.

Impact

This change aligns the error handling of invoice payment attempts with that of direct charges, returning a card_error when a charge is declined. You can now expect consistent error responses across different payment endpoints, improving error handling and debugging processes.
