not 17f1f2f809 docs(nav): publish every ADR and runbook, gated by a nav check (closes #169) (#172)

## What & why

`docs/` is the source of truth (CLAUDE.md §12), but only pages listed in `mkdocs.yml`'s nav
are published — and mkdocs' own `validation.nav.omitted_files: warn` keeps the build green
while dropping the rest. So the site had quietly stopped at **ADR-0010** and
**`runbooks/ci.md`**: 31 pages, including every ADR from 0011 to 0034, six of the seven
runbooks, and `synthetic-data.md`, existed in the repo and nowhere else.

- `infra/check-docs-nav.py` fails when a page under `docs/` is not in the nav. It runs in
  `make lint`, so the existing CI job gates it — python3 only, no new tooling, and no
  mkdocs install needed to check it.
- The nav now lists all 34 ADRs, all 7 runbooks and `synthetic-data.md`.
- ADR-0033's `Slice:` header said "none yet"; #25 closed it.
- The landing page gained a pointer to the Talos runbook.

Closes #169

## Definition of Done

- [x] Linked Gitea issue (above).
- [x] Failing test committed before the fix — the red commit lists all 31 missing pages.
- [x] Implementation makes the test pass.
- [x] Conventional Commits referencing the issue (`refs #169`).
- [ ] CI green — awaiting the run on this PR (`python3 infra/check-docs-nav.py` passes locally;
      `make lint` also needs the .NET SDK, which CI has).
- [x] `docker compose up` unaffected — docs and `mkdocs.yml` only, plus one `make lint` line.
- [x] Docs updated — that is the change.
- [x] No ADR needed: no dependency, no boundary, no §8 rule touched.
- [x] Not user-visible, so no demo note.

## Notes for reviewers

- The check is a **substring test**, not a YAML parse (there's a `ponytail:` note in the
  script): a page's path either appears in `mkdocs.yml` or it doesn't. That keeps it
  dependency-free — `mkdocs.yml` can't be read by `yaml.safe_load` anyway, it carries a
  `!!python/name:` tag for the mermaid fence. It does not check that an entry *points at a
  file that exists*; mkdocs' `not_found: warn` covers that direction.
- ADR labels in the nav are shortened by hand (`"ADR-0013: Behandel-portal wiring"`), since
  several H1s are a full sentence.

**Known gap, not fixed here:** CLAUDE.md §12 says the site is "published via a Gitea Actions
workflow to Gitea Pages", and no such workflow exists — `mkdocs build` is never run, by CI or
by any make target. Gitea has no built-in Pages, so publishing needs a decision (a
`gitea-pages` server, an artifact, or a static host) rather than a patch. Worth its own issue
if the published site is actually wanted; until then this PR makes the nav correct for whoever
runs `mkdocs serve`.Reviewed-on: #172

not 1dd8bd4e1b S-24/#25 · Helm chart + Kubernetes deployment, and Caddy for the portals (#166) (#167)
CI / lint (push) Successful in 1m17s
CI / build (push) Successful in 1m12s
CI / unit (push) Successful in 1m26s
CI / frontend (push) Successful in 2m58s
CI / mutation (push) Successful in 9m1s
CI / verify-stack (push) Successful in 8m53s
## What & why

Two changes, made and verified together on a real cluster.

**S-24 / #25 — a Helm chart for the platform.** One chart, `infra/helm/big-reference`,
whose `values.yaml` is a near-literal transcription of `infra/docker-compose.yml`, rendered
by three generic templates (Deployment, Job, Service) over a `workloads` map. Adding a
service is a values edit. `make k8s-lint` renders and schema-checks the whole stack without
a cluster. The issue asked for a *sketch*; this is deployed and verified end to end (see
below), which is more than it asked for — the part it asked for that is **not** here is the
production-posture write-up (HA, secrets, backup), see Known gaps.

**#166 — Caddy replaces nginx in the portals.** nginx resolves a variable `proxy_pass`
upstream itself, using only the `resolver` directive and never `/etc/resolv.conf`'s search
domains. That had cost two workarounds in one script: rewriting the resolver address for
rootless podman, and injecting a full FQDN so the bare `bff` name could resolve on
Kubernetes. Caddy dials per request through the system resolver, so `reverse_proxy
bff:8080` works on every engine unchanged; `apps/portal-nginx-resolver.sh` and the chart's
`BFF_HOST` env are deleted.

Closes #25
Closes #166

## Definition of Done

- [x] Linked Gitea issue (above).
- [x] Failing test committed before the implementation — twice: the Caddyfile contract test
      before the Caddyfiles, `make k8s-lint` before the chart.
- [x] Implementation makes the test pass.
- [x] Conventional Commits referencing the issues (`refs #25` / `refs #166`).
- [ ] CI green — awaiting the run on this PR (`make k8s-lint`, `dotnet format` and the new
      unit self-check pass locally; the compose e2e and mutation lanes are CI's).
- [ ] `docker compose up` from a fresh clone reaches green health checks within 3 minutes —
      the portal images were rebuilt and verified standalone, but a full `make up` run has
      not been done on this branch. Please confirm in review or let CI's smoke test speak.
- [x] Docs updated — `docs/runbooks/kubernetes-talos.md` (new), `frontend-decisions.md`,
      `demo-script.md`, and the docs that named nginx.
- [x] ADR added — ADR-0033 (chart) and ADR-0034 (Caddy).
- [ ] Demo note in `docs/demo-script.md` — not added: the deployment target is not a
      user-visible slice, and the Caddy swap is invisible to the demo script beyond the
      wording fix included here.

## How it was verified

Brought up from scratch on a single-node Talos v1.14.0 VM (6 vCPU / 10 GB, virtio disk)
under virt-manager: **29 pods ready and four bootstrap Jobs complete in under three
minutes, zero restarts**, using ~4.4 GB of the VM's 10 GB.

- Full Common Ground path: portal Caddy → BFF → domain → Flowable → ACL → OpenZaak +
  Objecten → NRC → event-subscriber → projection → public register (`INGEDIEND`, reference
  matching the submitted registration).
- Werkbak read with an MFA'd medewerker token → 200.
- The browser flow driven with Playwright against `http://localhost:30140`: secure context,
  `crypto.subtle` present, Keycloak form reached, login completed, **no console errors**.
- Routing checked against a stub BFF: SPA fallback serves deep links, each portal proxies
  its own groups, and a portal does *not* proxy a neighbour's group.

## Notes for reviewers

Three bugs this shook out, each fixed at the cause rather than the symptom:

1. **`command` vs `args`.** Compose's `command:` replaces the image CMD; Kubernetes'
   replaces the ENTRYPOINT. Transcribing one to the other broke every upstream image that
   relies on its entrypoint — postgres refused to run as root, Keycloak tried to exec
   `start-dev`. The chart now `fail`s at render time on `command`.
2. **Concurrent migrations.** Both `/setup_configuration.sh` and `/start.sh` run
   `manage.py migrate`; compose serialises them with `depends_on`, Kubernetes has no such
   edge, so the init Job and its web pod raced (`relation "zgw_consumers_service" already
   exists`). The four Django services now do both steps in order in the web pod — which
   also deletes four workloads.
3. **`emptyDir` databases are wiped by any pod-template change.** `make k8s-reseed` now
   also restarts `event-subscriber` and `projection-api`, which create the projection
   schema on start and otherwise keep writing to a schema-less database.

Known gaps / follow-ups:

- **Secrets.** `values.yaml` carries the dev credentials in plain text (`admin/admin`, the
  ZGW client secret, the two Objecten tokens) and the chart has no `Secret` objects. Fine
  for a laptop demo, and exactly what #25's "production posture" ADR should address — I
  suggest a follow-up issue rather than stretching this PR.
- **No CI gate for the chart yet.** `make k8s-lint` exists but is not wired into
  `.gitea/workflows/ci.yaml`, and nothing enforces that the chart and the compose file stay
  in step. Worth a small follow-up.
- **This is two slices in one PR.** They were built and verified together and the diff is
  entangled (the chart was written against Caddy from the start), so splitting now would
  mean re-creating an nginx-shaped chart to throw away. Happy to split if you'd rather.
- **Rebased onto #161** (merged as #165) rather than merged, to keep the history linear.
  One conflict, in the `unit:` target where both branches add a self-check line — resolved
  by keeping both. #161's `infra/host-browser.yml` arrived with
  `/usr/share/nginx/html/config.json` and is fixed to `/usr/share/caddy/` inside the
  `feat(portals)` commit, so no commit on this branch leaves that overlay pointing at a
  path the images no longer have.Reviewed-on: #167
