Phase 4B: Add Nostr notification listener to NanoNymManagerService
- Subscribe to NostrNotificationService.incomingNotifications$ in constructor - setupNotificationListener() processes incoming notifications - Matches notifications to NanoNyms by comparing Nostr public keys - Automatically processes notifications for all active NanoNyms - Add ngOnDestroy() for cleanup Notification flow now complete: Nostr → NanoNymManagerService → Storage
