orthodontics - events

Event	Direction	Payload
orthodontics.case_created	published	case_id, clinic_id, patient_id, appliance_type
orthodontics.case_status_changed	published	case_id, clinic_id, patient_id, previous_status, status, previous_finished_at
orthodontics.control_registered	published	case_id, control_id, clinic_id, patient_id, upper_wire, lower_wire, procedures, next_due

All three are consumed by patient_timeline (payload-only rows). Slice-b adds no new events; the recall upsert reuses the recalls module's own surface.
