feat: port نوبت‌ها (appointments) tab from tauri to patient detail page

Replace the placeholder row list on the patient detail «نوبت‌ها» tab with the
card-grid design ported pixel-for-pixel from clinic-pro-tauri TurnsSection:

- New AppointmentTurnCard mirrors tauri TurnsCard (success icon, title, date/time
  chips, personnel, status). Status uses the live AppointmentStatusDropdown
  instead of the tauri mock.
- New AppointmentsTab in PatientDetailPage: sort/filter toolbar (client-side) +
  reserve/new buttons linking to existing /admin/appointments pages + card grid.
- Add CalendarD/ClockP/UserD/StatusGlobe icons (verbatim from tauri).
- Backend: expose version on GET /patient/{uuid}/appointments so the status
  dropdown can optimistic-lock. No new endpoint.
- Tests: PatientAppointmentsTest (shape/version/order/empty/ownership) +
  AppointmentTurnCard + tab data/empty cases. docs/api/patient.md updated.
