Add SignalControl platform telemetry manifests

mail: remove cert-manager Certificate (manage mail-tls via step-ca JWK + noc1 renew timer)
step-ca-acme only has an HTTP-01 (Traefik) solver, but mail.iamworkin.lan must resolve to the dedicated MetalLB IP 10.0.56.202 (SMTP/IMAP), so HTTP-01 cannot validate (order stuck pending since 2026-05-06; cert expired 2026-05-24). mail-tls is now issued from step-ca's JWK 'admin' provisioner and auto-renewed by a systemd timer on noc1 that writes the mail-tls secret directly. The secret + Deployment mount + webmail IngressRoute are unchanged. Re-add a Certificate only if a DNS-01 solver is deployed for step-ca-acme. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

-# FlowerCore Brochure
-
-`apps/brochure` hosts the public brochure split from `FlowerCore.Intranet.Web`.
-ArgoCD's `apps/*` ApplicationSet will create `infra-brochure` after this
-directory lands on `main`.
-
-## Runtime
-
- Host: `https://brochure.flowercore.io`
- Namespace: `brochure`
- Deployment: `brochure-web`
- Image: `localhost/fc-brochure-web:v20260524-sprint32`
- Port: `8080`
- Public route method allowlist: `GET` and `HEAD`
-
-## Operator Actions
-
-1. Publish and import `localhost/fc-brochure-web:v20260524-sprint32` to every
-   RKE2 node before sync, using the same podman save + `ctr images import`
-   flow as the Intranet deployment.
-2. Create the Cloudflare DNS record for `brochure.flowercore.io` pointing at
-   the FlowerCore public edge.
-3. Verify `infra-brochure` appears in ArgoCD, the certificate becomes Ready,
-   and `GET https://brochure.flowercore.io/` returns `200`.
-
-The route intentionally does not expose `/ops/*` or `/admin/*`; the Brochure
-web app returns `404` for those paths and Traefik only forwards read methods.

+# FlowerCore SignalControl platform notes
+
+This app owns the cluster web manager at `signalcontrol.iamworkin.lan` and documents the physical Pi pilot at `signal-a.iamworkin.lan` / `pirelay`.
+
+## mTLS enrollment pattern
+
+Do not install or restart anything from this repo. The intended pirelay pattern is the Pi-signage step-ca-agent shape:
+
+- stable node identity: `pirelay`
+- local private key and CSR generated on the node
+- CSR submitted through the approved DeviceManagement/step-ca enrollment path
+- client certificate and chain stored node-local under `/etc/flowercore/signalcontrol/mtls/`
+- daily renewal timer, renewing only when fewer than 30 days remain
+- certificate used for DM-agent to DM-web traffic and future SignalControl inter-service calls
+
+Secrets, enrollment codes, private keys, p12 passphrases, and OIDC client secrets stay out of Git.
+
+## Telemetry
+
+Monitoring manifests add a dedicated Prometheus job:
+
+- `signalcontrol-pi-app`
+- target `10.0.58.113:5200`
+- path `/metrics/prometheus`
+- labels `instance="pirelay"`, `host="signal-a.iamworkin.lan"`, `service="signalcontrol-pi"`
+
+Host metrics continue through the `edge-nodes` node_exporter target at `10.0.58.113:9100`.
+
+## Physical-control audit
+
+The app ships with `FlowerCore:SignalControl:PhysicalAudit:Enabled=false` and `ForwardingEnabled=false`. Enabling local audit creates a SHA-256 hash chain for physical-control mutations. Forwarding to `https://audit.iamworkin.lan/api/v1/audit/signalcontrol` requires flipping the forwarding gate separately.
+
+Telemetry reads and `/metrics` scrapes are not audited.
