feat(lessonplan): 实现基于AI的学案自动生成与管理功能

- 新增DifyArticleClient工具类，实现基于Dify API的对话与文本生成功能
- 创建LessonPlansService接口及其实现，实现学案按天生成及存储
- 设计LessonPlansDO和StudentLessonPlansDO数据对象及对应MyBatis映射和数据库操作
- 扩展VocabularyBankDO实体及Mapper，支持查询单元词汇和学生未掌握词汇
- 利用deepoove-poi模板技术生成Word格式的学习计划文档，包含词汇、复习和练习
- 开发StringToPlanMapUtil工具类，解析AI返回结果为结构化学案内容
- 新增JUnit测试用例验证AI对话功能及学案生成逻辑正确性
- 更新Spring Boot配置，添加AI接口地址及密钥等参数
- 在前端Vue项目中新建学案页面，路由配置及导航菜单支持学案访问
