refactor(eq): 重构EQ页面及相关代码以优化PEQ管理与同步

- 禁用Vite配置中的manus debug collector插件，减少无用请求
- 对DeviceContext添加syncPeqCatalog方法用于同步PEQ状态
- 重构luxsinApi.ts中PEQ请求相关代码，统一POST请求封装，增强错误处理
- 将EQPage相关常量、工具和组件抽取至独立模块，简化主文件结构
- 使用缓存机制记忆预设滤波器列表，减少不必要的重复计算
- 优化PEQ状态同步逻辑，支持按模式（A/B）分别保存与应用滤波器
- 实现选择耳机型号时自动保存并更新对应滤波器缓存和显示
- 修改A/B切换逻辑，使用防抖同步和固定的peqApply调用
- 为音量滑块添加thumb-only滑动样式及拖拽区域限制，提升交互体验
- Home页面ListRow组件支持显示自定义缩略图
- 增加eq/constants.ts定义滤波器类型、参数范围和样式，统一管理配置
- 解决多处EQ页面组件交互和状态切换的潜在同步问题，提高代码维护性和可读性
