test(topology): cover compose labels and tolerate docker filter kwarg

test_compose asserts the new decnet.topology.* labels land on both base

(service=true). The stub docker client in test_deploy grew a filters
kwarg so it keeps matching the real .networks.list(filters=...) call
signature now used by the deployer.
