Runs as a host-level systemd timer on CT122 (scripts/discover-devices.sh)
rather than inside the api container, since real ARP entries live in the
host's network namespace, not Docker's bridge network. See
docs/device-discovery.md for the full writeup, including why literal
passive-only ARP reading was dropped (near-empty result in practice).
API reads the resulting JSON file each poll cycle, cross-references
config/hosts.yaml's knownDevices list by IP, and serves /api/devices.
Dashboard gets a new "Network Devices" table.
Closes#9.

Extends monitoring to the two bare-metal boxes Proxmox can't see.
Uses a dedicated ed25519 key with a forced authorized_keys command
(see docs/ssh-collector-key-setup.md) so a leaked key can only ever
run the fixed read-only stats script, never arbitrary commands.
CPU is approximated from 1-min load average / core count (a true
utilization % would need two /proc/stat samples).
Closes#8.
