Split the rootless network-driver knob out of network_docker into a
dedicated advanced subcategory (configs/network/network_rootless), marked
**ADVANCED** at both the file-header and field level so it's hidden behind
the advanced toggle in the WebUI. Registered in the network .category
order after network_docker. Pure config relocation — the install script
reads CFG_ROOTLESS_NET as a sourced var, so no script change needed.
