Automate VM provisioning via serial console
Replaces SSH-based installation with serial console automation using a new send_line_to_vm function. The script now logs in, installs Podman, downloads and installs UniFi OS Server, and retrieves the VM IP address directly via the console. This simplifies the process and removes SSH and sshpass dependencies.
