fix(secretary): gate CRUD action buttons across all panel pages by permission

Backend already returned 403 for ungranted secretary actions, but the UI still
showed the add/edit/delete buttons (e.g. clinic-services showed «بخش جدید» to a
secretary without services.create). Sweep every secretary-reachable page so each
create/edit/delete/manage control renders only when the matching
usePermissions().can(resource, action) is true. Owner/doctor/clinic are
unaffected — can() returns true when there is no permission context — so this
restricts only secretaries and mirrors the server checks.

Pages/components gated (resource):
- services: ClinicServicesPage, ServiceDetailPage (+ its tabs)
- inventory: InventoryPage, InventoryItemsTable, InventoryActionsMenu, PackagesView
- tags: TagsSettingsPage · staff: StaffPage · discounts: DiscountTab
- sms: SmsWalletPage · insurances: TenantInsuranceContracts
- clinic_doctors: ClinicDoctorsPage + ClinicDoctorsManager (props, default true)
- patients: PatientsListPage, MyPatientsPage, PatientDetailPage (records/notes/
  sessions/attachments/calls/wallet — create/update/delete split)
- appointments: AppointmentsPage (add + empty-slot booking gated by create),
  TurnsTable (status dropdown → read-only badge without update_status; actions
  menu hidden without manage/cancel)
- appointment_settings: AppointmentSettingsPage + ClinicAppointmentSettingsPage
  pass readOnly to ScheduleSection + FreeVisitPrice (new readOnly prop)

Not gated: view/read, search, filter, tabs, navigation, export, and modal
submit buttons reachable only via an already-gated trigger.

tsc clean; full frontend suite 501/501 passes.
