feat: complete NIP-47 Nostr Wallet Connect implementation in Quartz

Implements the full NIP-47 specification with all request methods,
response types, notification events, and JSON serialization.

New request methods:
- pay_invoice (updated with amount, metadata params)
- pay_keysend (amount, pubkey, preimage, TLV records)
- make_invoice, lookup_invoice, list_transactions
- get_balance, get_info
- make_hold_invoice, cancel_hold_invoice, settle_hold_invoice

New response types:
- Success responses for all methods above
- NwcErrorResponse (generic error for any method)
- NwcErrorCode enum with UNSUPPORTED_ENCRYPTION

New event kinds:
- NwcInfoEvent (kind 13194) - wallet service capabilities
- NwcNotificationEvent (kind 23197) - NIP-44 encrypted notifications
- Legacy kind 23196 support for NIP-04 notifications

New data models:
- NwcTransaction (shared invoice/payment object)
- TlvRecord (for keysend TLV records)
- Notification types: payment_received, payment_sent, hold_invoice_accepted
- HoldInvoiceAcceptedData with settle_deadline

Tags (following NIP-88 pattern):
- EncryptionTag for encryption scheme negotiation
- NotificationsTag for supported notification types

Updated:
- LnZapPaymentRequestEvent: generic createRequest() with NIP-44 support
- URI parser: lud16 parameter support
- Jackson deserializers: all methods routed correctly
- EventFactory: new kinds registered
