Wire phase-1 plugin-based auth into both Jellyfin instances so browser users
sign in via Authentik OIDC (jellyfin-plugin-sso) and native/app-password clients
authenticate through the Authentik LDAP outpost (jellyfin-plugin-ldapauth),
JIT-provisioning users.
Both instances share the single Authentik "jellyfin" OAuth2 client, so the SSO
config is identical; each reads the shared client_secret from its own
namespace-scoped Vault path via a per-namespace VaultStaticSecret.
- plugin-configmap.yaml: SSO-Auth.xml (OID provider "authentik", issuer
identity.k8s.syd1.au.unkin.net/application/o/jellyfin/, EnableAllFolders,
groups-claim role mapping akP-jellyfin-admin->admin / akP-jellyfin-user->user),
LDAP-Auth.xml (server authentik-ldap.authentik.svc:6636 LDAPS,
CreateUsersFromLdap), and branding.xml with a "Sign in with SSO" login link to
/sso/OID/start/authentik.
- statefulset.yaml: inject-plugin-config initContainer renders the XMLs into
/config/plugins/configurations/, substituting client_secret / ldap_bind_password
from the VSO-synced Secret (never committed) before Jellyfin starts.
- vaultstaticsecret.yaml: per-namespace oauth-credentials VSS.
Image tag is intentionally left at v0.1.3; the plugin DLLs land via a separate
jellyfin-ha release and a follow-up pin bump.
## Why
Rebuild the adult media instance as `fafflix`, mirroring the kids instance (`cheeztv`) HA pattern (Postgres-backed jellyfin-ha fork, Valkey transcode-lease store, shared-RWX transcode, CNPG + k8up/restic backups, static CephFS media PVs). Ben: "replace the adult jellyfin with the same pattern as kids." The adult instance holds no data currently, so the wipe/replace is sanctioned.
Stacked on top of `benvin/cheeztv` (#413) — base is that branch, not main.
## How
- Add `apps/base/fafflix/` — cheeztv pattern with `s/cheeztv/fafflix` on names/namespace/labels/secrets/buckets and the Vault kv path `kubernetes/namespace/fafflix/default/k8up-restic`.
- Media: mount the shared movies/tv CephFS subvolumes' `adult` subtree at `/media/movies` and `/media/tv`, plus the `kids` subtree at `/media/movies-kids` and `/media/tv-kids` (same two static PVs, new unique volumeHandles `fafflix-media-{movies,tv}-static`) so fafflix can resume kids content started on cheeztv. All media mounts readOnly, matching cheeztv.
- **Hostname preserved:** fafflix keeps serving the legacy jellyfin host `jellyfin.k8s.syd1.au.unkin.net` (TLS secret `fafflix-tls`, cert-manager re-mints). The dedicated fafflix domain switch is explicitly deferred — no `fafflix.unkin.net` created.
- config PVC on `cephfs-raid5-delete` (delete variant).
- Remove `apps/base/jellyfin/` + its overlay; swap `jellyfin`->`fafflix` in the `media-apps` ApplicationSet directory glob and the `media` AppProject namespace destination.
- Third-party images stay canonical upstream; the in-house `jellyfin-ha` image ref is unchanged.
## Verification
- `kustomize build` + `kubeconform -strict` clean on the fafflix overlay and the whole media appset scope (fafflix/cheeztv/arrstack): 0 invalid, 0 errors.
- No dangling `apps/base/jellyfin` references; `jellyfin.k8s.syd1.au.unkin.net` now served by exactly one app (fafflix); no `fafflix.unkin.net` anywhere.
