Clean up code to resolve all compiler warnings

- Remove unused AlarmStorage module and all references
- Remove unused imports (AlarmAction, AlarmTrigger, VAlarm from backend)
- Remove unused ReminderType enum from event form types
- Remove unused methods from AlarmScheduler and NotificationManager
- Fix unnecessary mut on NotificationOptions
- Simplify alarm system initialization in app.rs
- Remove unused variable assignments
