- list is_executor and ExecuteTicket both required an execute-step
approval record; tickets created without a workflow (default flow)
had none, so the execute button never appeared and the API returned
403 for everyone - admin/dba are now implicit executors (approved
status only, consistent in both list enrichment and execution check)
- status labels: pending/reviewing/approved were all shown as 审核中;
now 待初审/审批中/待执行 so the ready-to-execute state is visible
- verified end-to-end on test backend: create -> quick review dialog
with comment -> impact-summary execute confirm -> success, detail
page stage steps reach 完成 with execute result visible
