feat(phpipam): pull Valchedrym devices from OpenWRT DHCP/ARP via SSH

- CronJob now SSHs to Valchedrym OpenWRT (192.168.0.1) to pull DHCP leases + ARP table
- Parses /tmp/dhcp.leases for hostname + MAC, /proc/net/arp for additional devices
- London still uses ping sweep via pfSense WG tunnel (no SSH access to GL-iNet)
- 6 Valchedrym devices tracked: router, alarm, video, termoregulator, 2 clients
