Make the expanded location editor read like /config: Connection and Retention now use the section header + .domains-divider layout, and Connection gets a description. Move the retention 'Backup style' guidance into a tooltip and drop the always-visible hint line below it. Move the Enabled toggle out of the Connection fields into the collapsed location row header so a location can be enabled/disabled without expanding it; setLocationEnabled persists the change via the same config_update routing as saveSection.
