fix: 修復後端編譯錯誤，清理已刪除 Flashcard 屬性的引用 

- 修復 StatsController 中對已刪除復習屬性的引用
  - 將 LastReviewedAt 改為 UpdatedAt
  - 移除 MasteryLevel, TimesReviewed, TimesCorrect 引用
  - 使用 IsFavorite 和 IsArchived 作為簡化狀態邏輯
- 修復 DramaLingDbContext 中的 StudyRecord 和已刪除屬性配置
  - 清理 ConfigureFlashcardEntity 中已刪除屬性的欄位映射
  - 移除 ConfigureStudyEntities 方法（StudyRecord 實體已刪除）
  - 移除 StudyRecord 關係配置
- 後端現已成功編譯並運行在 http://localhost:5008
