cmdModel() had the only two root-absolute fetch('/api/...') calls left in the
frontend. Under a reverse proxy that mounts the app at a subpath (e.g.
jupyter-server-proxy at /proxy/<port>/), a root-absolute path escapes the mount
and 404s, so /model can't load the catalog or update the session. Resolve both
against document.baseURI (falling back to location.href) like every other fetch
in the frontend already does.
