fix: properly cancel alarms using FLAG_NO_CREATE and pendingIntent.cancel()

- Use FLAG_NO_CREATE to get existing PendingIntent instead of creating new one
- Call both alarmManager.cancel() AND pendingIntent.cancel() (matches scheduleExactNotification pattern)
- Fixes issue where cancellation failed, causing idempotence check to skip scheduling

Previously, cancelNotification():
- Used FLAG_UPDATE_CURRENT which could create new PendingIntent
- Only called alarmManager.cancel(), not pendingIntent.cancel()
- Result: PendingIntent still existed after cancellation, causing 'duplicate schedule' skip

The fix:
- Use FLAG_NO_CREATE to get existing PendingIntent (don't create if missing)
- Call both alarmManager.cancel() and pendingIntent.cancel() (matches pattern in scheduleExactNotification)
- This ensures proper cancellation so new alarms can be scheduled

This fixes Test 1 failure where alarms weren't appearing after scheduling.
