feat: 新增语音记录饮食功能与开发者调试模块

- 集成 @react-native-voice/voice 实现中文语音识别，支持“一句话记录”餐食
- 新增语音录制页面，含波形动画、音量反馈与识别结果确认
- FloatingFoodOverlay 新增语音入口，打通拍照/库/语音三种记录方式
- 添加麦克风与语音识别权限描述（iOS Info.plist 与 Android manifest）
- 实现开发者模式：连续三次点击用户名激活，含日志查看、导出与清除
- 新增 logger 工具类，统一日志存储（AsyncStorage）与按级别输出
- 重构 BackgroundTaskManager 为单例并支持 Promise 初始化，避免重复注册
- 移除 sleep-detail 多余渐变背景，改用 ThemedView 统一主题
- 新增通用 haptic 反馈函数，支持多种震动类型（iOS only）
- 升级 expo-background-task、expo-notifications、expo-task-manager 至兼容版本
