feat(phpipam): bidirectional DNS sync + Kea DHCP for 192.168.1.x

Browse source 
- CronJob now pulls hostnames FROM Technitium INTO phpIPAM for unnamed entries
  (reverse sync: Kea DDNS registers → Technitium PTR → phpIPAM hostname)
- Kea DHCP4 now serves 192.168.1.0/24 via pfSense WAN (vtnet0)
- 42 MAC→IP reservations for all known LAN devices
- Kea DDNS registers 192.168.1.x hosts in Technitium (forward + reverse)
- DHCP pool .150-.199 for unknown devices
- Technitium update ACL extended to include 192.168.1.2 (pfSense WAN)
