refactor(nostr): Reduce noisy logging in notification service

- Removed excessive logging for every event received in nostr-notification.service.ts.
- Changed logging for receivedEvent to only log on the first event from each relay.
- Made decryption failure logs silent, as these are expected for events not intended for the current user.
