feat: 完成CardSet功能清理和測試資料優化

## 主要改動

### 後端 CardSet 功能完全移除
- 刪除 CardSet.cs 實體模型
- 移除 Flashcard 中的 CardSetId 欄位和導航屬性
- 清理 User 實體中的 CardSets 導航屬性
- 更新 DbContext 移除 CardSet 相關配置
- 修復 FlashcardsController、StatsController、StudyController 中的 CardSet 引用
- 創建和執行資料庫 migration 移除 CardSet 表和相關約束

### API 功能修復和優化
- 修復 FlashcardsController GetFlashcards 方法的 500 錯誤
- 恢復例句圖片處理功能 (FlashcardExampleImages)
- 增強錯誤日誌和調試資訊
- 簡化後重新添加完整圖片處理邏輯

### 前端測試資料完善
- 轉換 CSV 為完整的 API 響應格式
- 為所有詞彙添加圖片資料結構和URL
- 修正 exampleTranslation 為 example 的正確中文翻譯
- 更新 review-design 頁面支援動態卡片切換
- 移除 cardSetId 相關欄位

### 系統架構簡化
- 移除不使用的 CardSet 功能，專注核心 Flashcard 學習
- 統一資料格式，提升前後端一致性
- 完善測試環境的假資料支援
