For jobs-only stacks, named_volumes_from_pod_files() returned empty
because it only scanned parsed_pod_yaml_map. This caused ConfigMaps
and PVCs declared in the spec to be silently skipped.
- Add _all_named_volumes() helper that scans both pod and job maps
- Guard update() against empty parsed_pod_yaml_map (uncaught 404)
