bpg/proxmox generates cloud-init network-config (static IP/gw/DNS) and
meta-data natively from the VM initialization block, so remove
network-config.yaml.tftpl and meta-data.yaml.tftpl. The rich first-boot
baseline (users, SSH key, packages, kernel modules, Longhorn /dev/vdb
mount, swap-off) is preserved and shipped as a user-data snippet
referenced by initialization.user_data_file_id. Comments updated
(libvirt -> Proxmox); /dev/vdb still valid (data disk is virtio1).
