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
- Implement Signal-like local-only notifications via direct WebSocket relay polling
- Poll every 60s foreground, 15min background, no external push server
- Resolve NIP-05 display names for notification body (e.g. 'alice@nostr.com reacted to your post')
- Add Capacitor LocalNotifications plugin with POST_NOTIFICATIONS permission
- Replace default Capacitor splash with Mew logo PNG on dark background using Android 12 Theme.SplashScreen
- Add ic_stat_mew vector drawable for notification small icon
- Regenerate splash PNGs with #14161f background
- Change STICKY_HEADER_CLASS to use 'top-mobile-bar sidebar:top-0'
- Matches the pattern used in Feed and NotificationsPage
- On mobile: sticky tabs position below the MobileTopBar (accounting for safe area)
- On desktop: sticky tabs position at top-0 (no top bar on desktop)
- Fixes issue where safe-area-top created unwanted space above tabs
- Update STICKY_HEADER_CLASS constant to include safe-area-top
- Fixes sticky tabs in Search and Settings pages on mobile
- Ensures sticky headers respect device notches and status bars
- Feed and NotificationsPage already use top-mobile-bar which includes safe area
- Change icon background from white (#ffffff) to dark theme (#14161f)
- Update capacitor.config.ts backgroundColor to match
- Update generate-icons.sh to use dark theme color
- Regenerate all Android icons with new background
- Prevents white-on-white icon appearance
