feat(android): implement cancelAllNotifications() method
- Add cancelAllNotifications() method to DailyNotificationPlugin
- Cancels all AlarmManager alarms (exact and inexact)
- Cancels all WorkManager prefetch/fetch jobs by tag
- Clears notification schedules from database (sets enabled=false)
- Idempotent - safe to call multiple times
- Implementation details:
- Reads scheduled notifications from database
- Uses NotifyReceiver.cancelNotification() for each scheduled alarm
- Includes fallback cleanup for orphaned alarms
- Cancels WorkManager jobs with tags: prefetch, daily_notification_fetch,
daily_notification_maintenance, soft_refetch, daily_notification_display,
daily_notification_dismiss
- Disables all notification and fetch schedules in database
- Add required imports:
- android.app.PendingIntent for alarm cancellation
- androidx.work.WorkManager for job cancellation
- Error handling:
- Gracefully handles missing alarms/jobs (logs warnings, doesn't fail)
- Continues cleanup even if individual operations fail
- Comprehensive logging for debugging
Fixes:
- 'not implemented' error when host app calls cancelAllNotifications()
- Enables users to update notification time without errors
- Allows users to disable notifications completely
- Prevents orphaned alarms and jobs after cancellation
The method matches TypeScript interface and is ready for use.
