System-config backups (libreportal backup system) carry no app slug, so the
notification descriptor resolved a blank subject + no icon, and a system-only
pick collapsed to `backup all` when no apps were installed. Give them the
LibrePortal icon + a "Configs" subject, add backup-system to the system-task
logo detection, and guard the whole-fleet collapse on having >=1 app. Rename
the visible subject from "System config" to "Configs" throughout the backup UI.
