feat(student): 新增学生详情接口及相关服务层支持

- 优化ClassDOMapper，重命名查询方法为selectClassDOById，并移除多余CRUD方法
- 新增ClassService接口及ClassServiceImpl实现，用于通过ID查询班级信息
- 新增GradeDO及GradeDOMapper，实现根据班级ID查询年级信息
- 新增GradeService接口及GradeServiceImpl实现根据班级ID查询年级数据
- StudentDO增加isDeleted和startTime字段，补充学生实体
- StudentDOMapper新增selectStudentById方法实现单个学生信息查询
- StudentService及其实现类新增getStudentById方法提供学生单条数据查询
- StudentController新增/detail接口，实现学生详情查询，返回学生姓名、班级、年级等信息
- 创建FindStudentDetailReqVO和FindStudentDetailRspVO用于请求和响应数据传输
- enlish-vue端新增getStudentDetail接口调用 后台学生详情接口
- 修改ExamWordsDetailCard组件，展示学生姓名及其班级、年级信息，新增fetchStudent异步方法拉取学生详情数据并显示
