feat: Enhance peer subscription and logging in Nostr chat

- Improve the subscription process for peers by adding detailed logging for subscription attempts and results.
- Update the ChatComponent to provide a summary of successful and failed subscriptions.
- Enhance the useNostrChat composable with additional logging for subscription filters and incoming message handling.
- Ensure better visibility into connection state changes and subscription readiness.
