Generates a docker-compose.yml from a DecnetConfig.

Network model:
|
|
Each decky gets ONE "base" container that holds the MACVLAN IP.
|
|
All service containers for that decky share the base's network namespace
|
|
via `network_mode: "service:<base>"`. From the outside, every service on
|
|
a given decky appears to come from the same IP — exactly like a real host.
