via "我的提醒" list instead). Reorder delete operation to remove
scheduler job before DB record, preventing orphaned list entries.

- Add snooze.py handler: prompts user for snooze minutes and schedules
a one-shot job with a cancel button (cancel_snooze_<id>)
- Refactor callback.py: support compound action prefix parsing for
cancel_snooze_*, switch snooze action to prompt-based flow
- Add snooze_action_keyboard() in keyboards.py; update snooze button label
- Register handle_snooze_input in group=1 to avoid ConversationHandler conflict
- Filter completed once-type reminders from get_user_reminders()
- Fix DateTrigger: compare and localize once_time in UTC consistently
