feat(cloud): single-shot deploy.sh + FROST stack + healthchecks

Stage 5 — make the cloud composition spin up in one command and add
the SensorThings (FROST) stack as a fully segregated tenant.

cloud/deploy.sh — idempotent, 7-step bring-up:
  preflight → validate → up + wait → cert state → issue/renew →
  service status → endpoint smoke test. Reissues LE cert only when
  current issuer no longer matches ACME_CA_URI. Move-aside-then-
  restore-on-failure so the bootstrap cert survives a failed certbot.

stacks/frost — new stack, segregated from shared sql/rabbitmq:
  - dedicated postgis container (frost-db)
  - dedicated internal mosquitto bus (frost-mosquitto)
  - frost-http + frost-mqtt on a private frost-internal network,
    joined to cloud-app only for nginx ingress at frost.wbd-rd.nl
  - shared mosquitto stack deleted; rabbitmq remains the only public
    MQTT broker (mqtt.wbd-rd.nl:8883 via stream proxy)

stacks/sql — pg_isready healthcheck so keycloak/gitea/mlflow can gate
on service_healthy via cloud-level depends_on overrides.

stacks/nginx-proxy:
  - nginx-init service generates a self-signed bootstrap cert on
    fresh deploy so nginx starts before certbot has issued a real one
  - frost.wbd-rd.nl vhost (/FROST-Server → frost-http:8080,
    /mqtt → frost-mqtt:9876 WebSocket)

stacks/mlflow — custom Dockerfile (upstream + psycopg2-binary) so the
official image can speak to the shared sql backend.

stacks/jupyterhub — DummyAuthenticator stub gated by
JUPYTERHUB_ADMIN_PASSWORD; TODO comments point at OIDC + DockerSpawner.

stacks/rabbitmq — config/{enabled_plugins,rabbitmq.conf} stubs
(management + mqtt plugins, MQTT auth required).

stacks/portainer — ports unpublished; nginx now the only ingress.

stacks/node-red — pin to 4.1 (the floating "4" tag does not exist).

 # Cloud / Central layer composition.
-# Includes all cloud-relevant stacks and defines the 4-network topology.
-# Run: cp .env.example .env  &&  docker compose up -d
+# Pulls in every stack that runs on the central hub and adds cross-stack
+# dependencies (the per-stack composes stay standalone-runnable).
+#
+# Fresh-deploy procedure (see ../docs/architecture.md for the long version):
+#   1. cp .env.example .env  &&  fill secrets
+#   2. Set DNS A records for the 10 short subdomains + vpn.wbd-rd.nl
+#   3. docker compose up -d
+#      - nginx-init creates a self-signed bootstrap cert
+#      - sql comes up, init.d/01-databases.sh provisions per-app DBs
+#      - keycloak / gitea / mlflow wait on sql healthcheck before starting
+#   4. ./deploy.sh — single command. Brings everything up, runs first-time cert
+#      issuance via certbot HTTP-01 (SAN over all *.wbd-rd.nl), reloads nginx,
+#      smoke-tests every vhost. Idempotent; safe to rerun.
+#   5. Flip ACME_CA_URI from staging → prod in .env, ./deploy.sh again.
