4K: pre-create download-client completed category dirs in playbook

radarr-4k/sonarr-4k surfaced 'download client places downloads in X but it
does not appear to exist' health errors: the SABnzbd (movies-4k/tv-4k) and
Transmission (radarr-uhd/sonarr-uhd) completed-category dirs dont exist until
the first grab lands in each category. On a rebuild those errors recur until
downloads happen. Add an idempotent file: task creating all four at
1000:3000 (abc:media) 0775 to match the /data tree.

Root cause of the original root:0770 drift on movies-4k: a manual
docker exec <client> mkdir runs as ROOT in linuxserver images (umask 007),
not as the app user abc. Live dirs normalized via host chown (NFS honors
no_root_squash); both instances now report 0 download-client-dir errors.
