pve1 is a static/DHCP-reserved Proxmox host at 10.42.0.4 (previously
mislabeled 'joel' in some places). 10.42.1.1 is the UDM Pro gateway
IP, not pve1 -- OPNsense was retired in favor of Ubiquiti. Removes
the stale duplicate PVE1 DHCP reservation at 10.42.1.1 and drops the
now-redundant 'joel' entry from network.json (consolidated into
pve1).
