fix(mobile+backend): fix notification DNS, message page API bugs, add read-all

Android DNS fix (native_dio_adapter):
- Dart's getaddrinfo() fails on some Android 12+ devices when browser works
  fine — root cause is Dart native socket using different DNS path than
  Android Java stack; fix by using NativeAdapter (OkHttp) on Android
- Add native_dio_adapter ^1.5.1 to pubspec; enable in ApiClient for Android

Message page bugs (5 fixes):
- Fix offset->page: Flutter sent ?offset=0 but backend NotificationQueryDto
  uses page/limit (1-based); now sends ?page=1&limit=50
- Fix announcement tab API: Tab 2 now calls /api/v1/announcements (separate
  resource) instead of /api/v1/notifications?type=ANNOUNCEMENT
- Fix markAllAsRead routing: calls correct API based on active tab
- Fix markAsRead routing: announcement items use announcements API
- Fix detail navigation: passes NotificationItem as route argument

Backend notification-service:
- Add PUT /api/v1/notifications/read-all endpoint
- Add markAllReadByUserId() to repository interface + TypeORM implementation
- Add markAllRead() to NotificationService

i18n (4 languages): add time.justNow/minutesAgo/hoursAgo/daysAgo keys
