 开始回复可选 `type: text | image | video`。文本填写 `reply`。图片或视频复用频道消息上传接口，将返回地址填入 `image` 或 `video`，`reply` 可作为说明。旧请求省略 `type` 时按文本处理。保存后向该机器人发送 `/start`，回复和底部键盘会一起下发。
 
 多语言表单按按钮所在行和列对应中文、英文、越南语。批量保存时提交 `menus: { "zh": { ... }, "en": { ... }, "vi": { ... } }`，每个语言的 `buttons` 为二维字符串数组。未配置的语言可省略，旧客户端也可继续传 `language` 保存单一语言。
