feat: 优化 EventScrollList 分页控制器位置和样式

本次提交包含以下优化：

✅ 分页控制器位置调整
- 从底部移至顶部右对齐
- 使用相对定位 (Flex justify="flex-end")
- 移除 CardBody 顶部 padding (pt={0})
- 确保分页控制器紧贴顶部，无任何间距

✅ 箭头样式优化
- 调整箭头大小和颜色
- 使用毛玻璃效果背景
- 改善视觉层次和交互体验

修改文件：
- src/views/Community/components/DynamicNewsCard.js (CardBody pt={0})
- src/views/Community/components/DynamicNewsCard/EventScrollList.js (分页位置和箭头样式)
