The prompt backend-probe and execute_code each kept a private (key, default) table for
container_config and drifted from the terminal tool's: the probe omitted docker_network, so
under docker_network: false it started a bridge-networked container; execute_code omitted
docker_extra_args, docker_forward_env and docker_env, so a sandbox created from that path
lost the operator's settings. Both now call terminal_tool_backends._container_config_from_config.
Salvaged from #62023 by @sagitario-jpn (the probe docker_network fix), widened to the whole class.
