Ham Lab is meant to be lightweight; VMs, passthrough and their consoles
are too much. Removes the Virtualization tab, the incus package, the
/api/virt routes, the instance.* sensors and their alert default, the
virt-export command, the VGA console and the vendored spice-html5, and
VIRTUALIZATION.md. A saved instance-down rule is dropped on load.
Everything removed is kept, as it was, on the virtualization branch.
