Subject: Validate a payment request is still valid prior to payment

their wallet which is valid at that time but its expiration lapses prior to
the user authorizing the payment. This could lead to an unnecessary customer
service interaction.

 # Creates and signs one or more transactions that satisfy (pay in full) PaymentDetails.outputs
