fix: list/search quickSearch 参数名修正 + SQL 方言友好报错 + E071 传输请求改 IN

- list_objects: maxrow/name/type 改为 operation=quickSearch/query/maxResults/objectType，
  并剥离 NW 7.40/7.50 quickSearch name 里的本地化类型标签（如 "ZCL_FOO (Class)"）
- query_table_data: HTTP 400 转抛 SapCliError，说明方言限制（WHERE 仅 IN/LIKE），不再打堆栈
- _query_transport_request: E071 查询 WHERE 改用 IN(...)，区分「无」与「无法获取」
