Swap the restic core service for resticontainer
(ghcr.io/deytenit/resticontainer:0.19.1): per-service backup intent via
restic.* compose labels (paths / stop / pre+post hooks), docker socket +
/:/hostfs:ro to resolve container mounts to host paths and snapshot the
union in one restic run. backup/run drops explicit /data/tier1,2 args
(paths now come from labels), keeps init/forget/notify, and guards on a
fresh snapshot. Snapshots are stamped --host <node>.apex.ermnvldmr.com
--tag biweekly and written with --compression max.
