feat(ios): add error handling and integration tests
Implement comprehensive error handling and integration test suite: Error Handling (Section 8): - Add iOS-specific error codes to DailyNotificationErrorCodes: - NOTIFICATION_PERMISSION_DENIED - PENDING_NOTIFICATION_LIMIT_EXCEEDED - BG_TASK_NOT_REGISTERED - BG_TASK_EXECUTION_FAILED - BACKGROUND_REFRESH_DISABLED - Add helper methods for iOS-specific error responses - Enhance error handling in ReactivationManager: - Database errors handled gracefully (non-fatal) - Notification center errors handled gracefully (non-fatal) - Scheduling errors handled gracefully (non-fatal) - All errors logged, app continues normally - Partial results returned when operations fail - Update plugin methods to use iOS-specific error codes: - getNotificationPermissionStatus uses NOTIFICATION_PERMISSION_DENIED Integration Tests (Section 9.2): - Add DailyNotificationRecoveryIntegrationTests: - Full recovery flow tests (cold start, termination) - Error handling tests (database, notification center, scheduling) - App stability tests (no crashes, concurrent operations) - Partial recovery tests - Timeout handling tests - Test coverage: - 10 integration tests covering recovery scenarios - Error handling verification - App stability verification - Concurrent operation safety Completes sections 8.1, 8.2, and 9.2 of iOS implementation checklist.
