fix(rootless): run docker ps inside the install-user shell when restarting all containers

dockerStartAllApps expanded $(docker ps -a -q) in the outer control-plane
shell, which has no DOCKER_HOST and so hit the nonexistent rooted socket at
/var/run/docker.sock. In rootless mode that connection fails, the
substitution returns empty, and 'docker restart' is then called with no
arguments. Push the whole pipeline into dockerCommandRun (matching
dockerRestartApp) and guard with xargs -r so it runs against the rootless
socket and no-ops cleanly when there are no containers.
