<message>Add a new step-by-step guide for deploying the CM4 eMMC provisioning service on a new Proxmox instance, enhancing clarity for users. Update existing documentation to reflect changes in network configuration options, including the introduction of LAN subnet settings for DHCP and TFTP. Modify cloud-init scripts to ensure proper management of DNS settings and improve the handling of network interfaces. Additionally, enhance the toggle script for network boot to dynamically read the LAN gateway from configuration files, streamlining the setup process and improving user experience.
