A laser device is not a doctor, so booking one from the public site sent
resource_uuid and no doctor_uuid and got back "doctor_uuid یا resource_uuid
الزامی است" — a message telling the caller to send something it had already
sent. The panel path had resolved this from ClinicResource.supervisor since it
was written; only the public path had not, and the field was defined but never
read there.
A resource with no supervisor now gets its own message pointing at the actual
fix, instead of the generic one.
