Rename UnifiedQRPayment to UnifiedPayment

Rename the primary payment handler struct from UnifiedQRPayment to
UnifiedPayment. Also rename QRPaymentResult to
UnifiedPaymentResult. This change aligns with the prior module rename
and reflects that the component handles a broader range of payment inputs.
