feat(products): 成片库视频内联播放，去掉弹窗 + 自适应比例

- ProductCard: 缩略图区域改为 <video> 内联播放，点击播放按钮原生 controls
- 视频比例通过 onLoadedMetadata 动态获取，获取不到时默认 16:9
- ProductLibrary: 移除 playingProduct 状态和 VideoPlayer 弹窗组件
- products.css: .xx-product-thumb 去掉固定 9:16 aspect-ratio，
  新增 .xx-product-thumb-video 样式（object-fit: contain）
- 卡片网格保持 4 列，卡片高度自适应视频内容
