refactor: reorganize nip47 wallet connect package into subpackages
Split the flat nip47WalletConnect package into logical subpackages:
- rpc/ - JSON-RPC protocol models (Request, Response, Notification, NwcMethod, NwcErrorCode, NwcTransaction, etc.)
- events/ - Nostr event types (LnZapPaymentRequestEvent, LnZapPaymentResponseEvent, NwcInfoEvent, NwcNotificationEvent)
- cache/ - Decryption caches (NostrWalletConnectRequestCache, NostrWalletConnectResponseCache)
Root level keeps the entry points: Nip47WalletConnect (URI parsing), Nip47Client, Nip47Server.
Existing subpackages (tags/, kotlinSerialization/, jackson/) remain unchanged.
