fix: get_facts() reads physical hardware info from DMI sysfs via SSH

Browse Source 
vendor, model and serial_number now come from /sys/class/dmi/id/
(sys_vendor, product_name, product_serial) via SSH, reflecting the
actual physical server rather than the Proxmox software layer.

Falls back to "Proxmox Server Solutions GmbH" / status.model if SSH
or DMI files are unavailable (e.g. bare-metal without SSH creds).
