fix(appointment): align request layer with real backend contract

- getAppointmentSlots uses doctor_uuid + date (was doctor_id, which the
  backend rejects with دکتر یافت نشد).
- postAppointmentPayment posts to /api/v1/payment/appointment (was the
  nonexistent /api/v1/payment).
- Remove getAppointmentNotAvailable: the not-available route does not
  exist (404); disabled dates come from the slots response.
