docs(media): the SSD metadata view has never been deployed on Dankserver

The vault described the overlay as the live shape. It is not: `media-view.sh
status` answers NOT MOUNTED, /var/lib/media-meta does not exist, and the
installed quadlets under ~/.config/containers/systemd still carry the pre-view
binds (/mnt/entropy:/data:ro for Jellyfin, /mnt/entropy:/mnt/entropy:ro for
Plex) while git binds the view with ConditionPathIsMountPoint. The deploy gate
(deploy-remote.sh:ensure_media_view) has therefore never run: the first
`deploy.sh dankserver --service jellyfin|plex` is an untested cutover of both
media servers, and Jellyfin's read-only sidecar error is today's expected state,
not a fault.

Same commit, the scan-acceptance law from tonight's TV handoff: it logged
`jellyfin scan: 401`, so Jellyfin never rescanned a 58k-move library until the
request was re-issued with the identical key and header form (204). Anything
that is not 204 means no scan was queued — re-issue, do not diagnose.
