fix(oci): upsert manifests and tags on push to handle re-pushes

Pushing the same image or tag twice caused a 500 panic due to unique constraint violations. Manifest insert now ignores conflicts (content-addressed, no update needed). Tag insert now updates the manifest reference on conflict so re-pushing a tag always resolves to the latest image.
