fix(infra): cap celery workers at 2 so the shared node stops OOM-killing CI (refs #182)

Unset CELERY_WORKER_CONCURRENCY makes oz-celery and nrc-celery fork one
process per CPU — 22 each on the lab node, ~225 MB apiece — and Talos'
OOM controller was killing the runner mid-verify-stack. Same lever as the
uWSGI caps (#144/#145/#147); objecten-celery already defaults to 1.

-# ADR-0035: The deployed stack is published through the existing labs Caddy
-
-- **Status:** Accepted
-- **Date:** 2026-09-25
-- **Deciders:** Respellion engineering
-- **Slice:** [#177](https://git.labs.respellion.tech/eho/register-referentie/issues/177) —
-  that issue proposed the opposite (an in-cluster Caddy edge); this ADR records why the
-  host-side option won. Implemented in #179, #180 and #181.
-
-## Context
-
-The stack deploys to a single-node Talos VM (ADR-0033, #175). Until now it was only usable
-through five SSH port-forwards: the portals' OIDC flow uses PKCE, PKCE needs
-`crypto.subtle`, and browsers expose that only in a **secure context**, meaning HTTPS or a
-`localhost` origin. A NodePort on the VM's address is neither. We want a URL a demo
-audience can simply open.
-
-Three facts about where things run shape the answer:
-
-- The Talos VM is a libvirt guest on a **Fedora hypervisor in the office**, behind NAT
-  with no public address. The only way in from outside is an existing reverse SSH tunnel
-  (`autossh-reverse-tunnel.service`) into an `openssh-server` container on the labs
-  server.
-- The **labs server** (public IP) already runs Caddy for `*.labs.respellion.tech`, with
-  the wildcard certificate (DNS-01 via Cloudflare) and ports 80/443. Every other labs
-  service is published there (repo `Infra`, `infra/development/`).
-- #177 proposed a Caddy **inside the cluster**, fed by a layer-4 forward on the host, so
-  that routing and certificates would be cluster state. That assumes the public IP is on
-  the hypervisor. It isn't: the hypervisor has no inbound path, and 80/443 on the labs
-  server are already taken by the labs Caddy.
-
-## Decision
-
-**Publish the portals and Keycloak through the existing labs Caddy. Carry the traffic to
-the cluster over a second reverse SSH tunnel from the hypervisor.**
-
-```
-browser ─https─▶ labs Caddy ─▶ openssh-server:3014x/30180
-        ─reverse SSH tunnel─▶ Fedora hypervisor ─▶ Talos NodePorts
-```
-
-- **Hostnames** under the existing wildcard: `big-register` (openbaar), `big-mijn`
-  (self-service), `big-behandel`, `big-beheer`, and `big-auth` (Keycloak, with `/admin*`
-  answered 404).
-- **Tunnel:** `big-portals-tunnel.service` on the hypervisor (repo `Infra`)
-  reverse-forwards the five browser-facing NodePorts into `openssh-server`. It is
-  separate from the access tunnel on `:6667`, so a failed forward can't cut SSH access.
-  Caddy joins the `openssh_default` network to reach the tunnel ends.
-- **Keycloak's issuer** is the public origin. The chart value `keycloakUrl` replaces
-  `host` + NodePort in one helper, `big.keycloakUrl`, which feeds both `KC_HOSTNAME` and
-  the portals' `config.json` authority, so the two cannot drift (ADR-0010). The deploy
-  workflow sets it from the `KEYCLOAK_URL` repository variable.
-- **`KC_PROXY_HEADERS=xforwarded`:** `KC_HOSTNAME_BACKCHANNEL_DYNAMIC` builds the token,
-  userinfo and certs URLs from the request. That request reaches Keycloak as plain HTTP,
-  so the URLs came out `http://` and browsers blocked them as mixed content. Trusting
-  Caddy's `X-Forwarded-Proto` keeps them HTTPS. In-cluster calls send no such header and
-  still use `keycloak:8080`.
-- **Demo MFA (optional):** `demo.otpAutofill` (`OTP_AUTOFILL`) makes the `big-demo` theme
-  (`infra/keycloak/themes/big-demo`) Keycloak's default. Its script fills in and submits
-  the medewerker OTP from the fixture secret (ADR-0031), so the step is visibly enforced
-  without an authenticator. It is off by default.
-
-### Alternatives considered
-
-- **In-cluster Caddy edge (#177, PR #178).** It would keep routes and certificates in
-  cluster state. But it needs a public inbound path to the hypervisor that doesn't exist,
-  plus a second certificate authority beside the labs Caddy, which already holds the
-  wildcard. Closed unmerged.
-- **Port-forward on the office router to the hypervisor.** This opens the office network
-  itself to the internet. Rejected.
-- **Move the cluster to a host with a public IP.** It would remove the tunnel, but it's a
-  bigger change than publishing one demo. It remains the natural step if the stack
-  outgrows a lab VM.
-- **Keep the SSH port-forwards.** Fine for one developer, but not something you can send
-  to someone.
-
-## Consequences
-
-**Positive**
-
-- Real hostnames and HTTPS, so PKCE works in any browser with no client-side setup.
-- No new certificate handling: the labs Caddy's wildcard covers the new hosts.
-- The chart stays edge-agnostic. With `keycloakUrl` empty it renders exactly as before,
-  so compose, CI and the `localhost` workflow are untouched.
-
-**Negative / costs**
-
-- **Routing lives outside the cluster**, in the Infra repo's Caddyfile. That is exactly
-  what #177 wanted to avoid. Adding a portal means changing three places: a NodePort in
-  the chart, a forward in the tunnel unit, and a host in the Caddyfile.
-- **Two SSH hops in the data path.** If the hypervisor or the tunnel is down, the
-  portals return 502 even though the cluster is healthy.
-- **One issuer string.** With `keycloakUrl` set, the `localhost` port-forward workflow
-  (runbook §5) can no longer log in.
-- **Keycloak trusts `X-Forwarded-*`** from anything that reaches it. Today that is only
-  in-cluster callers and the tunnel. `KC_PROXY_TRUSTED_ADDRESSES` can narrow it if the
-  NodePort is ever exposed more widely.
-- **The portals are public.** Anyone with the link can log in with the committed test
-  credentials, and with `OTP_AUTOFILL` on, no second factor stands in the way. That is
-  acceptable for synthetic data. Put the labs Caddy's Azure `authorize` in front of the
-  `big-*` hosts if the audience must be restricted.
-
-**Follow-up**
-
-- Runbook: `docs/runbooks/kubernetes-talos.md`, "Publishing through the labs Caddy".
-- Dev-mode Keycloak generates new signing keys on every restart, and the BFF re-fetches
-  them at most every 5 minutes, so expect a few minutes of 401s after a Keycloak restart.
-  Persisting Keycloak's database (runbook §6) would remove that.

-  clamd deployed in [#191](https://git.labs.respellion.tech/eho/register-referentie/issues/191) (S-28),
-  scanning wired in [#192](https://git.labs.respellion.tech/eho/register-referentie/issues/192) (S-29).
-
-## Context
-
-A zorgprofessional's diploma upload goes portal → BFF → Domain (`ProvideDocuments`) →
-ACL → OpenZaak. Nothing on that path looks at the file. It is not checked for malware,
-and nobody checks that it is a PDF. Behandelaars open these files later, so the
-register stores, and then serves, whatever a citizen sends.
-
-Scanning needs a signature engine that stays up to date. That means a new peer service,
-and that makes it an ADR (CLAUDE.md §14).
-
-## Decision
-
-1. **Engine:** the ClamAV daemon (`clamd`), official image `clamav/clamav`, pinned tag,
-   as its own service in compose and in the Helm chart. `freshclam` in the same container
-   keeps the signatures current, and they live on a volume.
-2. **Where the check lives:** in the **Domain Service**, behind an `IDocumentScanner` port
-   in `Big.Application`. "Only a clean PDF is stored and unblocks beoordeling" is a rule
-   of the provide-documents use case. The BFF is a thin proxy (§8.3), and the ACL
-   translates ZGW and nothing else (§8.1). A check in the domain also covers every
-   entry point, not just the portal.
-3. **Protocol:** the adapter in `Big.Infrastructure` speaks clamd's INSTREAM protocol over
-   `TcpClient`: `zINSTREAM\0`, length-prefixed chunks, a zero-length terminator, then a
-   `stream: OK` or `stream: <name> FOUND` reply. That is a few lines of code, so we add
-   **no NuGet package** for it (nClam and similar).
-4. **Fail closed:** if clamd can't be reached, the upload is refused (503). Nothing is
-   stored and the document wait stays open. We never store an unscanned file.
-5. **Type check:** content must also start with `%PDF-`, checked **after** the scan.
-   clamd matches EICAR (and many real signatures) only at the start of a file, so a type
-   check in front of the scan would report malware as merely "not a PDF". The check also
-   refuses a renamed non-PDF that is clean.
-
-## Consequences
-
-- One more long-running service. clamd holds its signatures in memory (about 1 GB idle).
-  `ConcurrentDatabaseReload no` stops a signature reload from holding a second copy,
-  but clamd pauses scans for the few seconds a reload takes. Compose caps it at
-  `mem_limit: 2g`, and the chart requests 1200Mi. This counts against the verify-stack
-  runner's memory ceiling (#182).
-- The first start downloads about 300 MB of signatures from the ClamAV CDN, so the
-  runner and the cluster node need outbound internet (as `seed-zaaktype` already does).
-  The CDN rate-limits by IP. A CI runner that starts fresh often can get throttled, and
-  then the health check doesn't go green. If that happens, mirror the signatures
-  (`cvdupdate`) rather than retrying.
-- Tests use the EICAR test string, built from two halves so the repo itself does not trip
-  an on-access scanner. No real malware is ever committed.
-- Infected or non-PDF uploads are refused with 422 and a business message. We don't keep
-  a quarantine copy: a refused file is simply not stored.

-## S-29 — Uploaded diplomas are virus-scanned (#192, ADR-0036)
-
-**Outcome:** a diploma upload is stored only when it is a PDF that **ClamAV** scans clean. If the file
-is infected, or not a PDF, the citizen is told why and the registration keeps waiting for a valid
-diploma. If the scanner is down the upload is refused (fail closed) and the citizen is asked to retry.
-
-```bash
-# 1. Manual: submit a registration in the self-service portal, then upload as the diploma:
-#    - any real PDF                    → "Uw documenten zijn aangeleverd."
-#    - the EICAR test file (below)     → "Er is een virus gevonden in dit bestand…"
-#    - a renamed .png                  → "Dit bestand is geen PDF…"
-printf '%s%s' 'X5O!P%@AP[4\PZX54(P^)7CC)7}$' 'EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*' > /tmp/eicar.pdf
-#
-# 2. Automated: clamd itself (EICAR → FOUND, clean → OK) and the use case at every refusal:
-make verify-clamav
-dotnet test tests/acceptance --filter "FullyQualifiedName~EenDiplomaAanleveren"
-```
-
-**The path:** portal → BFF → Domain `ProvideDocuments`. The domain asks `IDocumentScanner`
-(clamd over INSTREAM) first and checks `%PDF-` second, because clamd only spots EICAR at the start of
-a file. Only a clean PDF goes on to the ACL and into ZGW. Refusals come back as 422 with a reason, a
-scanner outage as 503 (ADR-0036).
