fix(networking): treat host-network services as host-exposed in summaries (#1430)

The exposure summaries derived a stack's exposure solely from the declared
published-port list, so a service running with network_mode: host (which
publishes every container port on the host but declares no ports:) was
under-reported as less exposed than it actually is.

Capture network_mode in the lightweight dependency parser, add an
isHostNetwork predicate, and treat a host-network service as exposed and
publishing across the Fleet networking summary, the Stack Dossier export, and
the Networking panel, matching how the Compose Doctor already flags host
networking.
