fix(admin): send visit_price_rials from appointment create modal & drawer

NewAppointmentModal and NewAppointmentDrawer never read the require-visit-
price setting nor sent visit_price_rials, so booking failed with 422
"هزینه ویزیت الزامی است" when the flag was on. Add a visit-price field
(prefilled from the free-visit price), require it when the flag is set, and
include visit_price_rials in the POST payload, matching AppointmentCreatePage.
