ui: config: move node ops (http-proxy) into existing "Authentication"

Mainly as Config -> Option is a weird name, Authentication has only
one obj. grid, the node options are only the http-proxy for now and
that is a sort of authentication, so good enough for me for now, but
should be rethought for 2.0 and/or once more node opts are added
