🎉 前端詞卡管理功能完全整合後端圖片資料

**圖片整合功能**:
- ✅ 更新Flashcard介面：添加exampleImages、hasExampleImage、primaryImageUrl欄位
- ✅ 取代硬編碼映射：getExampleImage和hasExampleImage改用API資料
- ✅ 詞卡列表頁面：完全使用動態圖片資料顯示
- ✅ 詞卡詳細頁面：修復資料載入邏輯使用列表API獲取圖片資訊

**詞性簡寫顯示**:
- ✅ 全域詞性轉換函數：getPartOfSpeechDisplay()
- ✅ 標準英語縮寫：noun→n., verb→v., adjective→adj.等
- ✅ 複合詞性處理：preposition/adverb→prep./adv.
- ✅ 應用到所有詞性顯示位置：列表和詳細頁面

**系統整合成果**:
- ✅ 完全移除硬編碼圖片映射依賴
- ✅ 前端直接使用後端API返回的圖片URL
- ✅ 支援AI生成圖片的即時顯示
- ✅ Mock資料相容性：添加圖片欄位避免錯誤

前端詞卡管理系統現已完全整合AI圖片生成功能！
