- hostfeatures.lua: replace basic-auth-only enforcement with a combined
apply_auth() that allows if EITHER basic auth OR a valid SSO session passes.
A "Basic" Authorization header takes the basic path (401 on failure);
otherwise a browser is 302'd to /__proxy_auth/start. SSO sessions are read
straight from Redis (proxy_SsoSession_<sid>, sid from the __proxy_sso cookie,
character-restricted) and matched to the host.
- proxy.conf: add a /__proxy_auth/ location (outside the gate) that forwards to
the nodejs app so the OIDC flow can run and set the cookie on every host.
- nginx.conf: add the proxy_auth_backend upstream (defaults to 127.0.0.1:3000).
Needs live verification on an OpenResty box (no Lua/nginx runtime in CI here).
