Add three new tests: - noop when healthy but docker inspect fails (returns True → don't churn) - build failure raises GatewayError - _ensure_network creates the network when it doesn't exist Also update the integration test to use new OrchestratorService API (infra_name/image instead of orchestrator_name/gateway_name/gateway_image). Brings diff-coverage from 86% to 90.3% against origin/main.
