fix(security): enforce ownership on 4 IDOR read/bind endpoints (M2-M5)

- M2 GET /insurance/{id}: was unguarded; now owner-or-admin (403 otherwise) —
  stops reading another doctor's negotiated price by id enumeration.
- M3 GET /clinic-pro/doctor-address/{id}: add the same owner/admin check the
  sibling PATCH/DELETE already had.
- M4 POST/PATCH /service-item: staff_uuid must belong to the caller's tenant
  (entity_type/entity_id) → 422; stops binding another tenant's staff.
- M5 appointment-settings list endpoints (date-override/holidays/
  available-locations): add the per-doctor ownership check the sibling
  single-record endpoints already enforce.

Regressions (6 negative cases fail without the fixes):
DoctorInsuranceOwnershipTest, DoctorAddressOwnershipTest,
ServiceItemStaffOwnershipTest, AppointmentSettingsListOwnershipTest.
