ghcr.io/oauth2-proxy/oauth2-proxy does not permit anonymous pulls (its
ghcr token endpoint returns DENIED), so artifactapi's anon-only ghcr
remote returns 401 and the sidecar is stuck in ImagePullBackOff. valkey-io
and other ghcr images work because they issue anon tokens.
Repoint the oauth2-proxy sidecar to the docker-internal local registry,
where the multi-arch v7.15.3 image (mirrored from quay.io, identical
digest sha256:10a11657...) is anon-pullable, restoring the arrproxy front
door.
