tts: bootstrap the chatterbox NFS subdir — first-window mount failed forever

First real window (2026-06-12 02:00): the chatterbox pod sat in
ContainerCreating with MountVolume exit 32 x19 — /srv/nfs-ssd is exported
whole-tree but the chatterbox SUBDIR never existed on the host (the
go-live runbook step needed NFS-host shell nobody doing the apply had).
One-shot busybox Job mounts the export root and mkdir -p's the subtree;
kubelet's mount retry then self-heals the pod. Audio queue (27 items)
drains as soon as the model loads.
