fix: pull registry-aware image name on local miss

When `image-repo` is overridden, the registry plugin pushes under that name and
the bare local `dokku/<app>:N` tag is never created. `fn-verify-app-image` now
queries the `deployed-app-image-repo` trigger and pulls `${REMOTE_REPO}${DEPLOYED_REPO}:${TAG}`,
retagging it as the local bare reference so subsequent inspects resolve. Also
aligns the `storage:ensure-directory` deprecation test assertion with the
standardized `Deprecated:` prefix.
