Add catalog/plex.yaml (kind: container) and its rendered apps/plex.yaml,
and wire apps/kustomization.yaml. Plex = docs/13 row 1, the catalog's
largest service; validates the public-exposure + config-on-Longhorn path.
- image plexinc/pms-docker (pinned recent stable tag), port 32400
- exposure: public at plex.home.keithjackson.dev; egress: internet
- auth: native (Plex accounts, not Keycloak — docs/13/15 exception)
- config PVC 20Gi on longhorn; off-cluster backup (daily-offcluster) as the
longhorn tier forbids reacquirable under L0 (R-STATE-03)
- observability up-SLI; update channel stable
Bulk media (R-STATE-04) deferred: the `bulk` StorageClass is a documented
stub (OQ-2 unresolved, NFS CSI not installed) so a bulk PVC would leave the
pod Pending. Media mount omitted; attach once bulk provisions.
Traces: R-GITOPS-02, R-NET-01/02/05, R-STATE-01/02/03, R-TLS/R-DNS,
R-OBS-01, R-UPD-01/03, R-IDP-02, R-PLAT-02.
