Replace JS WebView-based polling with pure native implementation: - NostrPoller: Java WebSocket client that queries Nostr relays directly via OkHttp - PollAlarmReceiver: AlarmManager fires every 60s, acquires WakeLock, runs native poll - NotificationService: foreground service keeps process alive, schedules alarms - MewNotificationPlugin: Capacitor plugin passes pubkey/relays from JS to SharedPreferences - Remove notificationService.ts (all polling logic now in Java) - Simplify useNativeNotifications to only configure native service + handle permissions
