feat: improve i18n implementation with better translations and accessibility

- Add proper i18n keys for language switcher tooltips and aria-labels
- Replace hardcoded Chinese console error messages with i18n keys
- Add missing translation keys for new UI elements
- Improve accessibility with proper aria-label attributes

+# CC Switch 国际化功能说明
+
+## 已完成的工作
+
+1. **安装依赖**：添加了 `react-i18next` 和 `i18next` 包
+2. **配置国际化**：在 `src/i18n/` 目录下创建了配置文件
+3. **翻译文件**：创建了英文和中文翻译文件
+4. **组件更新**：替换了主要组件中的硬编码文案
+5. **语言切换器**：添加了语言切换按钮
+
+## 文件结构
+
+```
+src/
+├── i18n/
+│   ├── index.ts          # 国际化配置文件
+│   └── locales/
+│       ├── en.json       # 英文翻译
+│       └── zh.json       # 中文翻译
+├── components/
+│   └── LanguageSwitcher.tsx  # 语言切换组件
+└── main.tsx              # 导入国际化配置
+```
+
+## 默认语言设置
+
+- **默认语言**：英文 (en)
+- **回退语言**：英文 (en)
+
+## 使用方式
+
+1. 在组件中导入 `useTranslation`：
+   ```tsx
+   import { useTranslation } from 'react-i18next';
+
+   function MyComponent() {
+     const { t } = useTranslation();
+     return <div>{t('common.save')}</div>;
+   }
+   ```
+
+2. 切换语言：
+   ```tsx
+   const { i18n } = useTranslation();
+   i18n.changeLanguage('zh'); // 切换到中文
+   ```
+
+## 翻译键结构
+
+- `common.*` - 通用文案（保存、取消、设置等）
+- `header.*` - 头部相关文案
+- `provider.*` - 供应商相关文案
+- `notifications.*` - 通知消息
+- `settings.*` - 设置页面文案
+- `apps.*` - 应用名称
+- `console.*` - 控制台日志信息
+
+## 测试功能
+
+应用已添加了语言切换按钮（地球图标），点击可以在中英文之间切换，验证国际化功能是否正常工作。
+
+## 已更新的组件
+
+- ✅ App.tsx - 主应用组件
+- ✅ ConfirmDialog.tsx - 确认对话框
+- ✅ AddProviderModal.tsx - 添加供应商弹窗
+- ✅ EditProviderModal.tsx - 编辑供应商弹窗
+- ✅ ProviderList.tsx - 供应商列表
+- ✅ LanguageSwitcher.tsx - 语言切换器
+- 🔄 SettingsModal.tsx - 设置弹窗（部分完成）
+
+## 注意事项
+
+1. 所有新的文案都应该添加到翻译文件中，而不是硬编码
+2. 翻译键名应该有意义且结构化
+3. 可以通过修改 `src/i18n/index.ts` 中的 `lng` 配置来更改默认语言
