refactor(showcase): rename open-gen-ui-advanced to emphasize frontend function calling

The advanced variant's distinguishing feature is that the agent-authored,
sandboxed UI can invoke frontend-registered sandbox functions via
Websandbox.connection.remote.<name>(args). The old label "(Advanced)"
did not convey this. Rename to "Open-Ended Gen UI (Advanced: with
frontend function calling)" in both the feature registry and the
langgraph-python manifest, and update descriptions to match. The id
stays `open-gen-ui-advanced` so URLs remain stable.

Regenerate derived bundles (registry.json, demo-content.json,
docs-status.json).
