refactor(payment): replace wait_any_incoming_payment with event-based system (#1019)

Browse Source 
Rename wait_any_incoming_payment to wait_payment_event and change return type
from WaitPaymentResponse stream to Event stream. This introduces a new Event
enum that wraps payment responses, making the system more extensible for
future event types.

- Add Event enum with PaymentReceived variant
- Update MintPayment trait method signature
- Refactor all payment backend implementations (LND, CLN, LNBits, fake wallet)
- Update mint and payment processor to handle new event stream forma
