feat ✨: Enable Wake-on-LAN persistently

This commit introduces persistent Wake-on-LAN support for Proxmox VE via Ansible. It includes YAML configuration options for the interface, verification, and systemd service management, ensuring reliable functionality after Ansible role execution. The changes also address ignoring outputs and temporary files for a cleaner setup.
