[Bug]: App Crashes When Setting Habit Reminder Frequency to "Once"

[runnnnnner200]

:writing_hand: Describe the bug

When modifying a habit reminder, selecting the frequency as "Once" causes the app to crash due to a SecurityException related to missing the SCHEDULE_EXACT_ALARM permission.

:bomb: Steps to reproduce

1. Create any habit.
2. Edit the habit reminder.
3. Set the reminder frequency to "Once".

:wrench: Expected behavior

The app should handle this case properly by either requesting the required permission or falling back to a non-exact alarm scheduling method if the permission is missing.
