[4+2h.] manifest job creation

При выборе в выпадающем списке в 5с имени Controlled zone (Asset.Template.Step), в БД манифеста автоматически создается соответствующая Job

The issue describes automatic job creation in a manifest database when a Controlled zone is selected from a dropdown. Look at the frontend dropdown component (likely in a React or similar UI) that triggers an API call to the backend. In the Django REST Framework backend, find the view or serializer handling Asset.Template.Step selection. Check the models for Manifest and Job to understand the relationship and where the job creation logic should be added. Verify by testing the dropdown interaction and checking the database for the new job entry.
