feat: 重新设计PaginatedRow组件，优化首页热门板块的切页体验

新功能:
- 实现无限循环翻页，不再局限于有限页数
- 重新设计翻页按钮，使用紫色渐变和更好的悬停效果
- 按钮位置居中对齐，放在两行内容的中间位置
- 为每个组件实例添加唯一ID，避免跨板块悬停效果冲突

 设计改进:
- 按钮使用渐变背景和阴影效果，提升视觉体验
- 优化按钮尺寸和间距，更加美观
- 改进页码指示器的动画效果
- 修复悬停状态下其他板块也高亮的问题

 Bug修复:
- 解决鼠标悬停在一个影视卡片时其他板块卡片也高亮的问题
- 修复只能显示两批内容的限制，现在支持无限循环
- 优化按钮定位，确保在各种屏幕尺寸下都能正确居中
