VSN-2434/ fix(planning): Fix header trip count consistency and pull-to-refresh scopingfix(planning): fix trip count display and pull-to-refresh issue
Summary :
- Invalidate planning cache automatically after absence create, update, or cancel so the trip list refreshes immediately with the new absence state
- Fix header trip count: use current month's filtered count (absence-aware) instead of the raw all-time count — count was inconsistent when navigating months
- Fix pull-to-refresh: refresh the currently viewed month instead of always defaulting to the current calendar month
- Fix document email: show a confirmation alert when the email is successfully sent
