fix: LiteLLM OIDC + Admin UI fixes - Authentik integration restored

Browse Source 
- Added extra_hosts for auth.sysloggh.net to LiteLLM container
- Fixed DOCS_URL=/docs (was /litellm/docs - path mismatch)
- Added Authentik self-signed cert to CA bundle
- Added nginx auth proxy for token/userinfo endpoints (SSL verify off)
- Changed OIDC token/userinfo endpoints to use nginx internal proxy
- Admin UI serving correctly on :4001/ui/ and /litellm/ui/
- Swagger API docs working at /docs and /litellm/docs
- ReDoc API docs working at /redoc and /litellm/redoc
- OIDC login flow verified working end-to-end
