These three containers were writing multi-GB/day of unbounded logs
(authentik_server 3.5GB, immich-server 2.3GB, owncloud_mariadb 2.1GB),
a major contributor to a recent 100% disk-full incident. Daemon-wide
default (max-size 10m, max-file 3) was also added to
/etc/docker/daemon.json on valhalla, but that only covers newly
created containers going forward -- these three need the explicit
per-service override since they're long-running and won't be
recreated otherwise.
