fix(compose): adapt relay/start tests to the container-spec layering

Rebasing onto main pulled in the relay work (added after this branch
was cut), whose tests build ServiceConfig/PreStart literals against
the flat, pre-layering shape: DependsOn/Networks set directly, and
PreStart typed as []ServiceHook. Both are incompatible with the
ContainerSpec/WorkloadSpec split this branch adopts -- the promoted
DependsOn/Networks fields need go1.27 to set via a flat literal (this
module stays on 1.26.3), and PreStart is now []PreStartHook, a full
container specification, not a plain hook.
