feat: 实现音乐记录展开播放功能和互斥展开系统

重构音乐管理界面，实现高级交互体验：
- 为当前选中音乐添加展开/收起按钮，默认展开状态
- 为我的音乐添加展开/收起按钮，默认收起状态
- 实现互斥展开逻辑：两个区域只能有一个展开
- 音乐记录展开时显示具体的声音组件和播放按钮
- 添加播放音乐记录功能：一键加载保存的声音配置

技术架构改进：
- 使用React hooks管理复杂的状态逻辑和互斥展开
- 统一的CSS变量系统管理背景色和组件样式
- 完整的错误处理和用户交互反馈
- 优化动画效果和视觉过渡体验
- 重构组件结构，提升代码可维护性

用户体验优化：
- 直观的展开/收起视觉反馈
- 平滑的动画过渡效果
- 清晰的操作流程和状态指示
- 统一的视觉设计语言
- 响应式布局适配不同屏幕

代码质量提升：
- 清除所有TypeScript和JSX语法错误
- 优化React组件的props传递和状态管理
- 统一的颜色变量和CSS类命名规范
- 完善的错误边界和异常处理机制
