- MCS150UpdateHandler is the catch-all for many admin-assisted DOT services
(UCR, MC authority, audit prep, ETA, name reservation, registered agent,
annual report). It was filling an MCS-150 PDF for ALL of them -- e.g. a UCR
order produced a wrong MCS-150 PDF. Now only MCS150_FORM_SLUGS fill the form;
others get an admin-review todo (PDF 'not generated') for manual handling.
Signature flow was already correctly scoped (UCR is not in DOT_SIGNING).
- handle_process_compliance_service forced the Sales Order workflow_state to
'Review' via set_value, which bypasses ERPNext's allowed transitions and
threw WorkflowPermissionError (Received -> Review) on every run. The Postgres
fulfillment_status is the source of truth; the ERPNext workflow_state is a
cosmetic mirror. Now try the proper apply_workflow action and stay quiet
(debug, not warning) when no valid Review transition exists.
