Migrate the four pause tests to the Scenario DSL: the invariant is the container state (paused/running), not an HTTP timeout, so the scenarios observe state and drop the port-mapping helpers and the pause fixture. ExitCode joins the check vocabulary for error-path steps, paired with MayFail. TestPauseServiceDoesNotExist now locks the current behavior — pause of an unknown service is rejected with 'no such service' — which resolves the TODO the legacy test carried: it asserted exit 0 while wishing for an error, and the CLI has since started validating selected services.
