unkin-agent 19f7afac92 Add shared arrstack Valkey and wire arr apps' Redis features (#394 )

Activates the arr forks (sonarr/radarr/prowlarr) #14 Redis features — SignalR backplane, cross-replica cache-invalidation bus, and distributed rate limiter — which ship deployed but inert because no Valkey exists in arrstack and nothing is wired to it. Ben wants ONE Valkey shared by all three apps.

## Changes
- Adds a single shared `ValkeyCluster` (`arrstack-valkey`) under `apps/base/arrstack/valkey/`, modeled on `jellyfin-valkey`: `shards:1`/`replicas:2` HA (one primary + two replicas, automatic failover), image via artifactapi (`artifactapi.k8s.syd1.au.unkin.net/dockerhub/valkey/valkey:9.0.0`), operator-default passwordless `default` user, node spread across hosts, cluster-aware PDB, ephemeral `/data`.
- Registers the `valkey` component in the arrstack base kustomization.
- Wires `<App>__Redis__Host` + `<App>__Redis__Port` into the `sonarr-env` / `radarr-env` / `prowlarr-env` ConfigMaps, all pointing at the shared service `valkey-arrstack-valkey.arrstack.svc.cluster.local:6379`.

## Notes
- Setting `Host` is the activation switch: the fork's `RedisOptions.IsConfigured` gates purely on a non-empty `Host`, so there is no separate Enabled flag.
- Passwordless (jellyfin parity — the operator leaves the `default` user without auth), so no `Password`/`Ssl` is wired and there is no secret to reference.
- One cluster is safe for all three: each fork namespaces its keys and pub/sub channels by a per-app prefix (`sonarr:ratelimit:` / `radarr:ratelimit:` / `prowlarr:ratelimit:`), so their state never collides.
- App `image:` (-unkin5), the waitfordb initContainer, and S3 buckets are untouched.
- Validated: `kubectl kustomize` renders clean for both `apps/base/arrstack` and `apps/overlays/au-syd1/arrstack`.

Follow-up: after merge, Valkey must come up and the three apps must roll (pick up the new env) before the #14 features can be validated live.
