Replace legacy jellyfin app with fafflix (adult, cheeztv pattern)

Rebuild the adult media instance as 'fafflix' following the same HA pattern
as the kids instance (cheeztv): Postgres-backed jellyfin-ha fork, Valkey
transcode-lease store, shared-RWX transcode, CNPG + k8up/restic backups,
static CephFS media PVs.

- Add apps/base/fafflix (namespace/labels/secrets/buckets/Vault path fafflix-*)
- fafflix mounts the shared movies/tv subvolumes' adult subtree at
  /media/{movies,tv} plus the kids subtree at /media/{movies,tv}-kids so it can
  resume kids content started on cheeztv; new unique static PV volumeHandles
- Keep serving the legacy hostname jellyfin.k8s.syd1.au.unkin.net (fafflix-tls);
  dedicated fafflix domain deferred, no new public host
- config PVC on cephfs-raid5-delete
- Remove apps/base/jellyfin + overlay; swap jellyfin->fafflix in the media
  ApplicationSet glob and AppProject namespace destination
- No data currently on the adult instance, so the wipe/replace is sanctioned
