feat(ios): update test app for iOS-specific methods and update checklist

Update iOS test app to use iOS-specific methods and remove Android-specific
code for better platform parity:

iOS Test App Updates:
- Remove Android-specific UI elements:
  - Removed "Exact Alarms" status (Android-only feature)
  - Removed "Channel" status (Android notification channels)
- Add iOS-specific UI elements:
  - Added "Background Refresh" status (BGTaskScheduler registration)
  - Added "Pending" notifications count display
- Replace Android-specific methods:
  - Removed isChannelEnabled() calls
  - Added getBackgroundTaskStatus() for background task registration
  - Added getPendingNotifications() for pending notification count
  - Updated loadPermissionStatus() to use getNotificationPermissionStatus()
- Update error handling:
  - Removed EXACT_ALARM_PERMISSION_REQUIRED error code references
  - Added iOS-specific error handling for NOTIFICATION_PERMISSION_DENIED
- Update checkStatus() handling:
  - Removed Android-specific fields (channelEnabled, exactAlarmsGranted)
  - Added iOS-specific status information (pending notifications)
- Add iOS-specific action buttons:
  - "Open Settings" button (openNotificationSettings)
  - "Background Refresh" button (openBackgroundAppRefreshSettings)
- Add iOS-specific helper functions:
  - loadBackgroundRefreshStatus() - checks BGTaskScheduler registration
  - loadPendingNotificationsStatus() - displays pending notification count
  - openNotificationSettings() - opens iOS notification settings
  - openBackgroundRefreshSettings() - opens Background App Refresh settings

iOS Implementation Checklist Updates:
- Mark integration tests as complete (DailyNotificationRecoveryIntegrationTests)
- Mark data conversion helpers as complete (DailyNotificationDataConversions.swift)
- Mark termination detection tests as complete
- Mark boot detection tests as complete
- Mark partial failure scenario tests as complete
- Update document version to 1.1.0
- Update last updated date to 2025-12-24

Achieves iOS-Android parity by using platform-appropriate methods and APIs.
