feat(integration-vm): force DHCP via explicit cloud-init network-config

Browse source 
Don't rely on the genericcloud image's network fallback; the seed now carries a
network-config forcing dhcp4 on en* interfaces. A correct prerequisite for the VM
to network once cloud-init processes the seed. (Note: a separate no-DHCP-lease
issue on first real boot is still under investigation — the guest isn't networking
and, under the no-sudo claude model, the VM console/logs aren't introspectable
without libguestfs; see next steps.)
