fix(monitor): 从界面上建的任务永远是小红书任务,平台从没被传上去
现象:站在抖音页面上新建任务,任务跑到小红书列表里去了;界面上还写着「笔记」。

根因在前端:TaskCreatePayload 里**根本没有 platform 字段**,handleSubmit 拼的 payload
自然也不带它,而后端是 `payload.get("platform") or PLATFORM_XHS` —— 于是不管在哪个
平台标签下建任务,落下来的都是小红书任务。以前只支持小红书,两边都看不出问题。

* TaskCreatePayload 补上 platform(并在注释里写明为什么它是必填),handleSubmit 带上
  当前平台。
* 更新任务时不带 platform:平台创建后不可更改,带着会让「平台能改」看起来像真的。
* 三处写死的「笔记」改成按平台取措辞(能力矩阵的 target_hints.note_label):
  · 任务编辑器的类型选择项「笔记(批量监控指定内容)」
  · 「笔记模式下此项不生效」那句提示
  · 任务卡片上的类型徽章 —— 它按**任务自己的**平台取词,不是当前平台,因为卡片未必
    只出现在同平台的列表里
  抖音管它们叫「作品」,小红书叫「笔记」,写死一个对另一个就是错的。

测试 +1:后端这一半也守住 —— 建任务时显式给了平台,就必须落到那个平台,且不得出现在
另一个平台的列表里。前端那半边是 UI,测不了,但后端守住能挡住「给了不用」这类退化。

注意:这次是纯前端漏传,后端那个「缺省回退小红书」的行为本身没变(有测试断言它是
有意为之的兼容行为)。要彻底消灭这类静默错误,可以把缺省值去掉、让 platform 必填 ——
那会破坏 API 兼容性,目前没有任何别的调用方,需要的话说一声。
