refactor: 优化代码结构和样式

- 在 `AiTaskServiceImplTest` 中注释掉 `isRetryableAsrQueryExceptionShouldTreatHttpTimeoutAsRetryable` 测试方法
- 在 `MeetingSummaryFileServiceImpl` 中重构代码以简化解析逻辑，并添加 `unwrapCodeFence` 方法
- 更新 `vite.config.ts` 中的代理配置，使用新的 IP 地址
- 调整 `MeetingPreviewView.css` 中的样式，包括宽度、背景色、边框颜色和阴影
- 增加 `audio-range` 的 Webkit 和 Firefox 样式定义
- 在 `MeetingPreviewView.tsx` 中添加 `useEffect` 以重置音频状态和同步会议时长
