unkinben ba7a1a9509 Enable Reloader secret watching, scope existing auto to configmap-only (#326) (#339)
## Why

The re-keyed internal `unkin.net` intermediate broke CA consumers (CNPG->RGW backups, subPath/startup-cached CA mounts) and needed manual pod restarts, because Reloader was deployed with `ignoreSecrets: true` and could not restart on the `vault-ca-cert` Secret. Enabling secret watching naively is unsafe: many workloads carry the generic `reloader.stakater.com/auto`, and the estate rotates numerous Secrets via Vault/VSO — those would restart on every rotation. This enables secret watching but scopes existing `auto` to ConfigMaps, making secret-reload opt-in per Secret.

## Changes

- Set `reloader.ignoreSecrets: false` (au-syd1 reloader-system values) so Secrets are watched.
- Convert every generic `reloader.stakater.com/auto: "true"` to the ConfigMap-only `configmap.reloader.stakater.com/auto: "true"` — 22 annotations across 19 files. Existing ConfigMap-reload behaviour is preserved; Vault/VSO Secret rotations no longer restart these workloads.
- Add explicit `secret.reloader.stakater.com/reload: "vault-ca-cert"` to the CA consumers that mount the CA and carry a Reloader annotation: `artifactapi/api`, `cephrgw-operator`, `puppetserver-master`, `puppetserver-compiler`, `litellm`, `logarchiver`.
- Add `secret.reloader.stakater.com/reload: "kanidm-tls"` so kanidm rolls when cert-manager renews its leaf.
- Add `docs/ca-rotation.md` runbook (indexed in `docs/README.md`).

## Safety review (secret-only / CA workloads)

`vault-ca-cert` is a plain reflected Secret that bootstraps Vault trust (not VSO-rotated; changes only on intermediate re-key). `kanidm-tls` is a cert-manager leaf. Everything else mounted (`environment`, `*-credentials`, `eyaml-keys`, `puppetboard-secrets`, `s3-credentials`, `nats-auth`, `clickhouse-credentials`, `woodpecker-*`) is VSO/CNPG Vault-rotated and deliberately excluded.

- `cephrgw-operator` — mounts only Secrets (`cephrgw-credentials` VSO + `vault-ca-cert`), no ConfigMap. Its old comment said "restart when the credentials Secret rotates"; `cephrgw-credentials` is VSO so that is now excluded, and reload is scoped to `vault-ca-cert` only. Comment updated.
- `nats` (logging) — old comment "Roll the StatefulSet when nats-auth changes"; `nats-auth` is VSO, so this is now ConfigMap-only (deliberately no roll on rotation). Comment updated. Same for the vector agent/aggregator/vm-ingest (VSO `nats-auth`/`clickhouse-credentials`).
- `artifactapi/ui` — mounts neither a ConfigMap nor a Secret; its `auto` was already a no-op. Left as ConfigMap-only.
- `puppetdb` / `puppetboard` — mount a ConfigMap plus VSO Secrets (postgres creds / puppetboard-secrets); ConfigMap-only is correct, no secret reload added.

CA consumers that mount `vault-ca-cert` but have **no** Reloader annotation (CRD-managed or startup-cached) are documented in `docs/ca-rotation.md` for manual restart rather than annotated here: `grafana`, `observability/vmagent`, `paperclip`, `argocd-repo-server`, plus CNPG clusters (`kubectl cnpg restart`).

## Notes / coordination

- Annotations left in their existing location (some sit on the pod template, e.g. `litellm`, `puppetdb`; Reloader reads controller-level metadata — placement unchanged from before, no regression).
- Touches `apps/overlays/au-syd1/logging/values-vector-*.yaml`, which overlap open PR #320 (Tier-2 Vector pipelines) — only the one-line reloader annotation is changed here.

## Validation

- `make kubeconform` — touched overlays (reloader-system, logging, woodpecker, authentik) valid; only the known-unrelated cattle-system rancher chart kubeVersion failure remains.
- `uvx pre-commit run --all-files` — all hooks pass.

Closes #326

unkinben d1a7646e09 Bump Woodpecker CI to v3.16.0 (#297)
## Why

Upgrade the Woodpecker CI instance from v3.14.1 to v3.16.0 to pick up upstream fixes and the k8s-backend privilege-escalation hardening (GHSA-qf34-295c-26v8). Server and agent must move together.

The chart is pulled at build time (`kustomize build --enable-helm`); the image tag defaults to the chart `appVersion`, so bumping the chart moves both images. Chart 3.6.5 -> appVersion 3.16.0 (verified against upstream `helm/charts/woodpecker/Chart.yaml`); subchart deps are unchanged from 3.6.3 (server 3.0.1, agent 2.0.1), so there is no values-schema migration.

## What

- Bump the woodpecker helmChart from `3.6.3` (appVersion 3.14.1) to `3.6.5` (appVersion 3.16.0) in the au-syd1 overlay. Server + agent both render as `v3.16.0`.
- Set `WOODPECKER_BACKEND_K8S_SERVICE_ACCOUNT_NAME_ALLOW_FROM_STEP: "true"` on the agent.

## CRITICAL: k8s backend serviceAccountName gating (required change)

v3.16.0 (PR #6792, GHSA-qf34-295c-26v8) gates step-level `serviceAccountName` behind a new agent flag `WOODPECKER_BACKEND_K8S_SERVICE_ACCOUNT_NAME_ALLOW_FROM_STEP`, **default `false`**. When disabled, any `backend_options.kubernetes.serviceAccountName` set by a pipeline is **silently ignored** and the namespace `default` SA is used instead.

Every terraform pipeline in the estate sets `backend_options.kubernetes.serviceAccountName` (e.g. `terraform-git`, `terraform-vault`, `terraform-artifactapi`) and relies on that SA for Vault k8s auth / Consul state. Without this flag those jobs would run as `default` and lose their Vault identity. This PR sets the flag to `true` to preserve current behaviour. No other newly-gated backend_options keys (pod labels/annotations from step, native secrets) are used by the estate.

## Migration / rollback

- **DB migration:** Woodpecker auto-migrates the schema (xorm) on server start; migrations are forward-only and NOT reversible. The 3.14 -> 3.16 changelogs do not call out a data-destructive migration, but a **DB backup (CNPG cluster `woodpecker`) should be taken before merge**.
- **In-flight pipelines:** merging rolls the server StatefulSet and agents; any running pipelines are interrupted and will need re-running.
- **Rollback:** re-pin chart `3.6.5` -> `3.6.3` reverts the images to v3.14.1, but because migrations are one-way, a clean rollback requires **restoring the CNPG DB from the pre-merge backup**, not just pinning the old image.

## Validation

- `kustomize build --enable-helm apps/overlays/au-syd1/woodpecker` renders `woodpecker-server:v3.16.0` and `woodpecker-agent:v3.16.0`; agent carries the new env var.
- `kubeconform` (k8s 1.33.7): 24/24 resources valid.
- pre-commit (yamllint + checks): all pass.

## Follow-up (not in this PR)

Woodpecker images are pulled from `docker.io` / `ghcr.io` directly, not the artifactapi proxy. Proxying them via artifactapi is a possible follow-up but out of scope for this version bump.

unkinben 1b781e0885 feat(woodpecker): set workflow pod priority class to power (#175)
## Summary
Sets `WOODPECKER_BACKEND_K8S_PRIORITY_CLASS: power` on the Woodpecker agent so all CI pipeline pods are scheduled with the `power` PriorityClass (value 100, preemptionPolicy: Never).

This means pipeline pods can be evicted when the cluster is under pressure but won't preempt other workloads.

## Dependency
Requires the `power` PriorityClass to exist on the cluster — deploy PR #174 (priority-classes app) first.

## Test plan
- Trigger a pipeline run and confirm pods are created with `priorityClassName: power`
- `kubectl get pod -n woodpecker -o jsonpath='{.items[*].spec.priorityClassName}'`
