- Fix NotificationService API calls to use flutter_local_notifications v21 named parameters - Expose nextInstanceOf as @visibleForTesting public method for unit testing - Create NotificationSettingsNotifier with @Riverpod(keepAlive: true) - NotificationSettings data class with enabled bool + TimeOfDay fields - Persist notifications_enabled, notifications_hour, notifications_minute to SharedPreferences - Sync default state in build(), async _load() overrides on hydration - Update tests to use correct Riverpod 3 provider name (notificationSettingsProvider) - Add makeContainer() helper to await initial _load() before asserting mutations - All 84 tests pass (72 existing + 12 new notification tests)
