fix(ios): resolve build errors and add missing configureNativeFetcher method

Fixed Swift compilation errors preventing iOS build:
- Added explicit self capture [self] in closures in DailyNotificationReactivationManager
- Removed invalid BGTaskScheduler.shared.registeredTaskIdentifiers API call
- Fixed initialization order in DailyNotificationModel (verifyEntities after container init)

Added missing configureNativeFetcher method to iOS plugin:
- Implemented method matching Android functionality
- Stores configuration in UserDefaults for persistence
- Registered method in pluginMethods array
- Supports both jwtToken and jwtSecret parameters for compatibility

This resolves the runtime error "configureNativeFetcher is not a function"
that was preventing the test app from configuring the plugin.
