feat(ios)!: implement iOS parity with BGTaskScheduler + UNUserNotificationCenter
- Add complete iOS plugin implementation with BGTaskScheduler integration - Implement Core Data model mirroring Android SQLite schema (ContentCache, Schedule, Callback, History) - Add background task handlers for content fetch and notification delivery - Implement TTL-at-fire logic with Core Data persistence - Add callback management with HTTP and local callback support - Include comprehensive error handling and structured logging - Add Info.plist configuration for background tasks and permissions - Support for dual scheduling with BGAppRefreshTask and BGProcessingTask BREAKING CHANGE: iOS implementation requires iOS 13.0+ and background task permissions
