feat(04-02): add widget tests for notification settings UI
- 5 tests for Benachrichtigungen section: header rendering, toggle OFF default,
time picker visibility on/off with AnimatedSize, formatted time display
- Uses notificationSettingsProvider.overrideWithValue for test isolation
- Uses themeProvider.overrideWithValue to avoid SharedPreferences dependency
- UncontrolledProviderScope + ProviderContainer follows home_screen_test pattern
- All 89 tests pass (84 existing + 5 new)
