fix(workflow): restore xfail on publish_request_approval with accurate reason

GET /workflow (publish approval state) and POST /workflow (set stage) are
separate ACL checks. The test account has set-stage permission but not
get-approval permission on DEV11, causing 401 regardless of workflow state.
The set_workflow_stage setup step is kept — it is still correct hygiene.
Unblock: grant Workflow > Publish Approval to Owner role in the test org.
