feat(schedules): add bulk delete via checkboxes

- Add BulkDeleteSchedulesTask, BulkDeleteSchedulesAction
- Add route DELETE /dashboard/schedules/bulk-destroy
- Add bulkDestroy method to ScheduleController
- Update Index.vue: select all/individual checkboxes, bulk actions bar
- Fix CheckDashboardPermission: replace naive /s$/ regex with Str::singular()
  to resolve irregular plurals (faculties→faculty, categories→category)
