feat: 优化素材库检索列表视图显示效果

列表视图重新设计:
- 采用水平布局：左侧缩略图 + 中间内容 + 右侧操作
- 紧凑的20x20图片尺寸，保持清晰度
- 优化信息层次：标题、描述、标签分层显示
- 右侧操作区域：颜色指示器 + 查看按钮 + 时间

 交互优化:
- 悬停效果：图片缩放、背景渐变、阴影变化
- 评分标识移至图片右上角
- AI推荐标识在悬停时显示
- 标签数量限制和省略显示

 布局改进:
- 列表项间距调整为3px，更紧凑
- 移除不必要的flex样式冲突
- 保持网格视图原有的卡片布局
- 响应式设计适配不同屏幕尺寸

现在列表视图更加美观实用，信息密度合理！
