fix: store appointment address from schedule and auto-add patient to clinic

Appointments now persist address_id resolved from the weekly-schedule
session (location_id) across all booking paths (online, secretary, admin).
On confirm, the patient is added to the clinic owning that address, or to
the doctor's single clinic as fallback. Weekly-schedule create/update now
requires location_id on every active session. PatientSession exposes
doctor_uuid/doctor_name so clinic records show which doctor each visit is for.
