The public list GET /api/v1/doctors only excluded inactive doctors
when an explicit `active` filter was passed; with no param it returned
everyone (deactivated doctors just ranked lower). Deactivated doctors
(admin toggled active_doctor_appointment off) leaked onto nobat724.
- DoctorRepository::findWithFilters: default (no `active` param) now
filters activeDoctorAppointment = true. The active=1 (bookable) and
active=0 (admin, inactive-only) escape hatches are unchanged.
- Doctor::toDetailArray: expose raw `is_active` (= activeDoctorAppointment,
independent of schedule) so public clients can 404 a deactivated
doctor's profile page; distinct from `active` (flag && has_schedule).
- Tests + docs/api/doctor.md updated.
