Enhance the NETWORK-BOOT-LXC.md documentation with detailed steps for testing network boot functionality, including prerequisites, expected outcomes, and quick testing methods. Introduce a new section on monitoring network boot status on the LXC, outlining commands to check DHCP leases, dnsmasq status, and registered devices. Update the initramfs scripts to support a rescue mode for devices stuck in network-only boot, allowing users to change boot order settings. Include a new rescue script for eMMC management in the build process.
