arrstack: add kids backend tier (sonarr/radarr/nzbget-kids) (#412)
Splits the arrstack media pipeline into an adult and a kids tier so kids content lives in its own libraries, databases, and downloader while reusing the shared prowlarr, CNPG cluster, Valkey, media PVCs, and S3 buckets. Backend workloads only — no routing/ingress, no arrproxy, no adult-instance changes in this PR. How: - sonarr-kids / radarr-kids: mirror the adult -unkin fork Deployments (same images/tags, 3 active-active replicas) on their own Postgres DBs (sonarr-kids-main / radarr-kids-main), UrlBase /3df803/sonarr and /3df803/radarr, and kids MediaCover/Backup S3 prefixes. - Media mounts use the tvshows/kids and movies/kids subPaths of the shared media-tv / media-movies PVCs, so kids libraries are isolated on the same CephFS subvolumes. - nzbget-kids: second downloader on its own RWO config PVC, completed downloads land in the kids media subtrees for same-filesystem hardlink imports. - postgres: two managed roles + Database CRDs and their VSO-synced <app>-kids-db credential secrets. - per-app VMPodScrape for each kids exportarr sidecar; new apps registered in the base kustomization. Validated: kustomize build + kubeconform (96/96 valid), yamllint + pre-commit clean.
