feat(web): 监控作品卡片展示描述，观看/点赞/评论/分享全宽 GRID 贴封面下方

- WorksGallery 卡片封面改走本地缓存 /works/:id/cover（WorkCover 与竞品分析页同链路，
  替换会过期的 douyinpic 签名 URL）
- 卡片新增作品描述（body，两行省略）
- 指标从标题下横排小字改为封面下方全宽四列 GRID（观看/点赞/评论/分享，上值下图标行）
- WorksGallery 为监控账号详情与自有账号详情共用，两处同步生效
- 测试：works-gallery-card 3 例 + 既有 1 例全绿，tsc/antd lint 通过
