unkin-agent d387301d6b arrstack: manage sonarr/radarr/prowlarr API keys via Vault (#369)
## Why

The sonarr/radarr/prowlarr images self-generate an API key into
/config/config.xml on first boot, so the key is unmanaged and differs per
volume reset. This makes Vault the source of truth for those keys (override
bootstrap, chosen by Ben): the key is minted in Vault and enforced into
config.xml before each app starts.

## Changes

- Add a `VaultAuth` `default` in the `arrstack` namespace (kubernetes auth,
  mount `k8s/au/syd1`, role `default`, SA `default`), mirroring jellyfin.
- Add a per-app `VaultStaticSecret` that syncs
  `kv/kubernetes/namespace/arrstack/default/<app>` (key `apitoken`) into the
  `<app>-apikey` Secret. The `default` k8s role's templated policy already
  grants read on that path for the `arrstack/default` SA, so no
  terraform-vault change is needed.
- Add an `apikey-init` initContainer to each of the three deployments that
  reads `API_KEY` from the VSO-created Secret, fails closed on a missing or
  non-hex value, and writes/updates only the `<ApiKey>` element in
  `/config/config.xml` (then fixes ownership 1000:1000, mode 600). Image is a
  pinned busybox via artifactapi to keep this PR atomic (no new image
  dependency).
- Wire the new manifests into the base and per-app kustomizations.

## Notes

- Keys already seeded in Vault at `kv/kubernetes/namespace/arrstack/default/<app>`.
- nzbget is out of scope: it has no config.xml `<ApiKey>` (uses ControlPassword),
  a separate follow-up.
- Downstream consumers (proxy, terraform) currently read
  `kv/service/media-apps/<app>`; the authoritative key now lives at the path
  above. Reconciliation is deferred.

unkin-agent fc08f1fecc arrstack: sonarr/radarr/prowlarr/nzbget on shared CephFS media (#366)
## Why
Stands up the download-automation stack (sonarr, radarr, prowlarr, nzbget) in a new `arrstack` namespace, sharing the same CephFS TV/movies subvolumes that jellyfin serves read-only (jellyfin static-PV rework is on the base branch, PR #237). Downloads and libraries live on one filesystem per media type so the arrs import with atomic hardlink moves.

## Changes
- Add `apps/base/arrstack/` namespace with its own static CephFS PVs (`arrstack-media-tv`, `arrstack-media-movies`) + RWX PVCs (`media-tv`, `media-movies`) bound to the same rootPaths jellyfin uses; each namespace gets a unique PV name/volumeHandle pinned by claimRef.
- Deploy sonarr (mounts media-tv RW), radarr (media-movies RW), prowlarr (config only), nzbget (both media PVCs RW); single replica, Recreate strategy, LinuxServer images via artifactapi dockerhub remote, PUID/PGID/TZ, probes, fsGroup for CephFS writability.
- Per-app config PVCs on `cephrbd-fast-retain` (RWO, 5Gi) for the SQLite state; internal-only Gateway + HTTPRoute per app (traefik-internal, vault-issuer, external-dns `<app>.k8s.syd1.au.unkin.net`), no oauth yet.
- nzbget: initContainer seeds `/config/nzbget.conf` (copy image template if absent, append managed path/category block once) and creates the media dirs; category `tv` -> `/media/tv/downloads`, `movies` -> `/media/movies/downloads`.
- Wire ArgoCD: add `apps/overlays/*/arrstack` to the media ApplicationSet. (media AppProject already gains the arrstack destination + PersistentVolume whitelist on the base branch.)

## Depends on
terraform-artifactapi PR #31 (allowlist `^linuxserver/` on the dockerhub remote) must be merged + applied before these pods can pull.

## Follow-up (terraform)
Root folders (/media/tv/series, /media/movies/films), download-client wiring (host `nzbget`, port 6789, categories tv/movies) and API keys are configured later via terraform-arr.
