fix(booking): aggregate public booking state across all schedules

The public doctor payload built `active`/`free_turn`/`hours_of_work` from the
personal schedule alone, so a doctor bookable only at a clinic was reported as
"نوبت‌دهی غیرفعال". Aggregate over every schedule instead: any schedule with
online booking on and an active day makes the doctor bookable, and the disabled
label only appears when all of them are off.

Three admin-panel fixes for the same class of bug:

- AppointmentsPage took the selected doctor from `dbUuid`, which is the clinic's
  uuid inside a clinic context — the slots request 404'd. Use `doctorUuid`.
- TurnsTimeline rendered any error or unknown empty_reason as "این روز شیفت کاری
  ندارد". Errors now surface as errors and unknown reasons get a neutral message;
  the day-off wording is reserved for an explicit day_off from the backend.
- Admins have no clinic context, so slots fell back to the personal schedule.
  They now pick a location from `appointment-booking-locations` and that choice
  drives the slot, service and create-appointment requests.

Adds `app:schedule:normalize-format` for legacy rows stored as a bare JSON list
covering only Saturday, which read as day-off for the rest of the week.
