fix(appointment): convert picker timestamp to date and fix summary panel

Follow-ups found while sweeping for stale shapes:
- The date picker emits a unix timestamp, but appointment-slots needs
  Y-m-d; convert with moment before calling (slots never loaded before).
- Appointment summary (information/Detail.js) used the auth-required
  getDoctorAddress and selectedSlot.time; derive the address from the
  loaded doctor.address by location_id and use selectedSlot.start_time.
- SendAppo: drop the dead postAppointment block, unused useParams/loading,
  and a duplicate disabled prop on the button.
