feat(student): 实现学生学习分析功能

- 新增AnalyzeStudentStudyReqVO用于分析请求参数封装
- StudentService接口新增analyzeStudentStudy方法及其实现
- 实现分析逻辑，查询最近7天学生考试及单词掌握记录，构造分析数据
- 通过DifyArticleClient调用外部AI服务生成学习分析结果
- 使用Redis缓存分析结果，设置3天过期
- 新增ExamWordsJudgeResultDetail和WordMasteryDetail数据模型
- Mapper新增支持根据学生ID和时间范围查询考试结果和单词掌握日志
- DifyArticleClient新增sendStudentAnalyze方法调用分析接口
- 前端学生页面新增学习分析面板及调用接口，支持超时设置
- 修改路由权限配置，允许访问学习分析接口
- 添加markdown-it库支持分析结果富文本渲染
- 移除RoleServiceImpl中redis设置过期时间，改为永久保存
