feat: 更新考试相关页面，添加刷新功能，修改考试状态显示

Browse Source 
- 注：当前代码还存在bug：查看结果暂出现错误。
- 在 SubjectSelectionPage 页面中添加刷新按钮，允许用户手动刷新考试任务列表。
- 修改 UserTaskPage 页面，重构考试任务为答题记录，更新数据结构和状态显示。
- 在 AdminDashboardPage、UserManagePage、UserRecordsPage 等管理页面中添加考试状态显示，使用不同颜色区分状态（不及格、合格、优秀）。
- 在 ResultPage 中显示考试状态，确保用户能够清晰了解考试结果。
- 添加约束，确保单次考试试卷中题目不可重复出现，并记录相关规范。
- 添加评分状态约束，根据得分占比自动计算考试状态，并在结果页面显示。
