fix(manuscripts): 我的稿件正文改用阅读抽屉渲染富文本

列表把 cms_manuscript.content 当纯文本输出，后台 wangEditor 存的 HTML
（<p>、<img>）和早期 AI 草稿的 markdown（##、**）都会原样露出来。

- 列表只留元数据：标题、首行摘要、状态、更新时间、字数；点一行从底部升起阅读抽屉
- 新增 components/manuscript-reader：mp-html 渲染正文（HTML / markdown / 纯文本按内容判定），
  支持长按选择、点击图片预览、复制标题、复制正文，有封面时展示封面
- 新增 utils/content-format：格式判定、纯文本化、渲染参数准备
- 搜索改为匹配标题 + 纯文本正文，不再直接匹配带标签的原始 content
- 正文每篇只解析一次（加载列表时），摘要、字数、搜索复用同一份纯文本
- 顺带修掉 hero 统计标签在浅色玻璃卡上不可见的问题

+ *   1) 后台 wangEditor 保存的 HTML（`<p>`、`<img src=...>`）；
+ *   2) 早期从 AI 结果直接粘进后台的 markdown（`## 标题`、`**加粗**`、`- 列表`）。
+ * 库里没有格式标记，所以只能按内容猜：能识别成 HTML 就按 HTML 渲染，
+ * 否则看是否带 markdown 记号，两者都不是就按纯文本兜底。

+ * 只做展示需要的粗粒度判定，不追求完整的 HTML / markdown 解析。
