JS attaches to its fetches — the dashboard route itself is unauthenticated
so an operator can open it in a browser and paste the token on demand.
A ```` matching the server's ``root_path`` is injected so the
page's relative fetches resolve correctly whether the control plane is
served at the root or reverse-proxied under a sub-path (e.g. ``/ingester/``).
