Neither chart bundles Lens anymore. The Lens subchart, its lock entry,
the vendored chart archive, the templates/lens resources and the
bundled-Lens install smoke are gone. A connection-only lens block wires
the gateway and backend to a Lens deployed from its own chart, and an
enabled lensWorker value fails the render instead of being ignored.
Supersedes #47869, which made the same change for helm/litellm only.
