Fix config status and missing historical filter imports

1) Added _get_active_jail_names import in jail_config_service 2) Added _get_active_jail_names and _parse_jails_sync imports in filter_config_service and resolved constants/exceptions 3) Added bangui_version=__version__ in config_service.get_service_status and tests
