The firewall rebuild chose ufw-docker vs ufw from $EUID -eq 0 (am I root?)
rather than the docker mode. During a rootless install everything runs as
root, so it wrongly picked ufw-docker — which manages the rooted daemon's
DOCKER-USER chain that rootless never creates — and failed with 'Docker
instance libreportal doesn't exist'. (It was also inconsistent at runtime: the
non-root cron refresh always fell through to plain ufw.) Select by
CFG_DOCKER_INSTALL_TYPE so rootless always uses plain ufw (ports are published
on the host) and rooted always uses ufw-docker.
Also: ufw-docker needs the container name, not the app name — pass
service_name (e.g. libreportal-service) with an app_name fallback; route the
traefik-detect docker ps through runFileOp (was raw docker -> /var/run in
rootless); and move the ufw/ufw-docker sudo calls to runSystem.
