fix lint errors from merge: duplicate def, shadowed import, empty f-string

- deployment_create.py: remove duplicate create_registry_secret signature
- deploy_k8s.py: rename loop var 'config' to 'svc_config' (shadowed import)
- deploy_k8s.py: remove f-prefix from string without placeholders
- deploy_k8s.py: suppress pre-existing C901 on _create_volume_data
