Unify the front-end UI shell across the theta42 apps

views/top.ejs, views/bottom.ejs and public/lib/js/app-base.js are now byte-identical across sso-manager-node, proxy and jump-host. Everything per-app moved into utils/ui.js, exposed to every render as `ui` via app.locals (nav items + their group gates, footer repo/docs/ToS links, favicon, profile/logout targets, update-banner on/off + label). Client framework changes: - One gating model everywhere: app-base.js reveals .group-required-<cn> for each of the current user user/me groups. sso-manager-node sends LDAP DNs in memberOf, the OIDC clients send CNs in groups; both normalise to CNs, and the clients isAdmin flag becomes a synthetic `admin` group, so proxy nav-admin items are now group-required-admin. - user/me is fetched once per page load and cached (app.auth.loadUser); nav, forceLogin and group-required elements all read that one promise. - isLoggedIn is dual-mode (Promise + node-style callback), so the async and callback call styles both work from one shared top.ejs. - forceLogin no longer uses $.holdReady (removed in jQuery 4): it redirects to /login?redirect=<path>, and still enforces required groups. - logOut only clears the session; the caller decides where to go next. - post/put/delete are dual-mode Promise/callback, which also removes the undefined `callback2` reference that threw on a non-function callback. Dependencies: jquery ^4.0.0 and ejs ^3.1.10 in all three apps. proxy specifics: - .group-required base rule added to styles.css; the admin nav items lost their inline display:none in favour of it. - The brand link points at / instead of #.
