docs(network): establish IP addressing scheme and update infra IPs

Browse Source 
Defines the new structured 192.168.2.0/24 layout:
- .10–.59   client DHCP (router-assigned, DNS → .253)
- .220–.229 virtual nodes (VMs / LXC containers)
- .230–.239 expansion buffer
- .240–.249 physical nodes (pve1 at .245, PBS at .244)
- .250–.253 network services (router .254, FreeIPA/DC .253)

Storage network 192.168.4.0/29 defined for HA DRBD replication
(internal vmbr1 bridge, no uplink). Host octet matches LAN throughout.

Updates variables.nix: pxeServerIp .247→.223, pbsIp .108→.244,
adds domainControllerIp .253. Updates pxe-boot.md IP references.
Full migration before/after table in docs/ip-addressing.md.
