z2m migrates configuration.yaml on startup and needs write access.
Remove the separate :ro config mount; rely on the base compose's
/opt/homelab/data/zigbee2mqtt/data:/app/data read-write mount instead.
configuration.yaml must exist at that path on the node before first run.

docker-compose v1 cannot clear the ports list from the base compose with
ports: [] in an override, so network_mode: host caused InvalidArgument.
Use extra_hosts with host-gateway instead: maps 'mosquitto' hostname to the
Docker bridge gateway IP so mqtt://mosquitto:1883 reaches the host-networked
mosquitto process from within the bridge-networked z2m container.
Requires Docker 20.10+ (present on chelsty-infra).

docker-compose v1 (1.29.2 on chelsty-infra) raises InvalidArgument when
network_mode: host is combined with port_bindings from the base compose file.
Add ports: [] in the override to clear the base ports list.
