[openshift_setup] Add catalog registry auth and signature policy bypass

When cifmw_openshift_setup_catalog_registry_credentials is defined:
- Merge the auth into the cluster pull-secret so nodes can pull from
  the Konflux image-rbac-proxy registry.
- Add the catalog registry to insecure and allowed registries to
  bypass image signature validation for Konflux-built FBC catalogs.
- Wait for MachineConfigPools to settle after IDMS + pull-secret
  changes before proceeding.
