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.
