feat(sso): wire Keycloak SSO end-to-end across all apps New stack: - stacks/oauth2-proxy/ — per-app sidecars (mlflow, portainer, rabbitmq) that gate vhosts via nginx auth_request against Keycloak's wbd realm. Native OIDC wired into: - grafana (generic_oauth, role-attribute-path → Admin/Editor/Viewer) - jupyterhub (oauthenticator.GenericOAuthenticator) - node-red (passport-openidconnect; in-memory state store + users() resolver because adminAuth doesn't expose req.session) - jenkins (oic-auth plugin via JCasC; matrix-auth for authz; setup wizard suppressed; custom image with plugins.txt) Infra fixes uncovered while bringing the above online: - nginx-proxy: bump proxy_buffer_size to 16k so oauth2-proxy callbacks don't 502 on the JWT-bearing Set-Cookie header. - nginx-proxy: add `resolver 127.0.0.11 valid=30s` so service names re-resolve after sidecar recreates (was cross-wiring oauth2-proxy upstreams after restart). - jupyterhub: pass --allow-root to the singleuser spawner (hub runs as root inside its container; jupyter-server refused root without flag). - jupyterhub Dockerfile: install jupyterlab + notebook so SimpleLocalProcessSpawner has something to launch. - node-red Dockerfile: install passport-openidconnect into the image so settings.js can require() it. - portainer: pre-seed local admin via --admin-password=<bcrypt-hash> so the 5-minute "no admin → lockout" timer can never trigger. - deploy.sh: restore executable bit (was 644 in repo). Admin/viewer policy: - Created realm role `app-admin` in keycloak wbd realm. - Grafana maps app-admin → Admin (default Viewer). - Jenkins matrix-auth grants r.de.ren Overall/Administer, authenticated users get Overall/Read + Job/Read + View/Read. - Node-RED: NODERED_ADMIN_USERS env list → permissions "*", others ["read"]. (TODO: switch to app-admin realm role.) - JupyterHub: JUPYTERHUB_ADMIN_USERS env list. (Same TODO.) - Gitea: r.de.ren pre-created as local admin; OIDC auto-links via email. Docs: - README, cloud/README, stacks/oauth2-proxy/README, and per-stack READMEs updated to reflect the new state and remove resolved TODOs. - cloud/.env.example gains all the new OIDC client + cookie-secret keys. - cloud/README documents the full kcadm realm bootstrap, including the hardcoded-audience mapper and post-logout redirect URIs that are non-obvious gotchas.

# oauth2-proxy — Keycloak SSO gate for apps without native OIDC.
# One container per protected vhost; each presents itself on the `app` network
# so nginx-proxy can hit it via auth_request.
