worker compose: run node-agent in host network mode

The agent now uses network_mode: host so os.hostname() and the network
interface list reflect the actual host instead of a per-container random
hex hostname (root cause of duplicate Zampp2 rows) and a 172.x docker
bridge IP. Also passes NODE_IP and BMD_MODEL through for explicit overrides.
