feat: reminder button in list/tabs view, notifications show reminders, trash count live update

- Add reminder action to NoteActions (masonry view) and NoteMetaSidebar (tabs view)
- NotificationPanel now fetches and displays upcoming/overdue reminders alongside share requests
- Badge count includes overdue reminders; overdue items show mark-as-done toggle
- Sidebar trash count refreshes on NoteRefreshContext trigger (no more manual refresh)
- Add "Clear completed" button on reminders page with clearCompletedReminders action
- Add i18n keys for new features (en/fr)
