fix(restore): stop containers with resolved compose stack

[patil2001]

Summary

stop_containers ran a bare docker compose down, but the repo ships no
top-level compose file, so -s/--stop-containers always failed with "no
configuration file provided" and the restore ran under live writes. Add
resolve_compose_flags and use it, mirroring ods-uninstall.sh.
