feat(api): 增强设备状态数据结构及PEQ请求处理

- 新增subwoofer相关参数及hearing数据支持
- 添加parseHearingData函数用于解析听力配置数据
- 扩展INPUT_LABELS支持HDMI-EARC，并新增Bluetooth和Headset索引常量
- 改进POST请求错误处理，增加请求失败时抛出异常
- 调整bootSound文档说明，指向固件特性配置
- 更新firmware版本格式化显示规则
- 增加音量直通模式和静音锁定逻辑的辅助函数
- 移除无用的dreMode和LED相关字段
- 更新MOCK_DEVICE_STATE样例数据匹配新结构和默认值
