完成 Batch 3：修復 4 個 API Controller 的 AsEnumerable 問題

Browse Source 
修復文件（共 17 處）：

1. supplierController.cs (6 處)
   - 移除簡單查詢的 AsEnumerable() (2 處)
   - AsEnumerable() → AsQueryable() (GetList, GetKindList)
   - 優化分頁查詢模式（Count + ToPagedList.ToList()）(2 處)
   - 修復 Split().Select().ToList() 類型問題

2. adminUserController.cs (4 處)
   - 移除簡單查詢的 AsEnumerable()
   - AsEnumerable() → AsQueryable() (GetList)
   - 優化分頁查詢模式
   - 重構複雜查詢：移除嵌套的 AsEnumerable()
     改為先 ToList() 再使用 Contains

3. orderdetailController.cs (3 處)
   - 移除 AsEnumerable()，改為在查詢末端使用 OrderBy
   - 優化分頁查詢模式
   - 修復 null-propagating operator：
     .FirstOrDefault()?.print_id → .Select(u => u.print_id).FirstOrDefault()

4. transfer_registerController.cs (6 處)
   - AsEnumerable() → ToList() (需要解密操作的情況)
   - 保留在必要時才轉換到內存操作
   - 確保數據庫查詢先執行

技術改進：
✓ 複雜嵌套查詢優化（adminUserController）
✓ 解密操作前置優化（transfer_registerController）
✓ Null-propagating operator 替換為安全的 Select
✓ 統一使用三元運算符處理分頁
✓ IEnumerable<int> → List<int> 避免類型轉換錯誤
