## 环境对象修复

为以下视图添加了 `@EnvironmentObject var languageManager: LanguageManager`:
- `QRCodeSavedView`
- `ImageComposerView`
- `BarcodeCharacterHintView`

并为这些视图的预览添加了 `.environmentObject(LanguageManager.shared)` 修饰符。

## 验证结果

- ✅ 项目编译成功
- ✅ 所有硬编码字符串已替换为本地化键值对
- ✅ 三种语言（英文、中文、泰文）的翻译完整
- ✅ 环境对象正确配置
- ✅ 预览功能正常工作

## 总结

本次全面检查成功修复了 **7个文件** 中的硬编码字符串问题，新增了 **25个本地化键值对**，确保整个应用的多国语言适配完整性。所有界面现在都能正确响应语言切换，为用户提供一致的多语言体验。
