R de Ren 33a794e35d 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.

infra

R&D infrastructure stacks for Waterschap Brabantse Delta. Hub-and-spoke deployment: one cloud central hub + per-plant edge sites.

Layout

infra/
├── stacks/         # reusable, runnable stack defs (kebab-case)
├── cloud/          # the single central hub
├── sites/          # per-plant edge deployments
└── docs/           # architecture + conventions

Stacks are pulled into the cloud and site composes via the Compose Spec include: directive. Each stack is also runnable standalone for testing.

Quick start

# Cloud hub (run on the central server)
cd cloud
cp .env.example .env       # fill in real secrets
./deploy.sh                # one-shot bring-up + Let's Encrypt + smoke test

# A plant edge (run on the edge gateway at the plant)
cd sites/<plant>
cp .env.example .env
docker compose up -d

After deploy.sh finishes, see cloud/README.md for the one-time Keycloak realm bootstrap that wires every app to Keycloak SSO.

Design

See docs/architecture.md for the hub-and-spoke topology, 4-network model, ingress table, and the reasoning behind each choice.

Conventions

kebab-case folder names
compose.yml (Compose Spec), not docker-compose.yml
Stack composes pulled into cloud/site via include:
Secrets in .env files (gitignored); .env.example committed with placeholders
OT layer (OPCUA, PLCs) is out of scope for this repo
