feat(exam): 实现考试阶段单词判卷与学生水平智能诊断

- 新增ActionType枚举定义系统动作类型
- 新增DiagnosisResult和ZoneStats数据模型支持诊断结果及区域统计
- 优化ExamWordsJudgeServiceImpl判卷逻辑，支持识别图片、更新考试判卷结果
- 基于分区词汇掌握情况，实现学生当前水平年级的智能判定
- 实现基于多分区准确率的升级、降级、复习和触发重测等动作建议
- 更新学生实际年级actualGradeId并展示在学生详情页面
- 修正ExamWordsConstant年级常量及年级名称映射方法
- 优化前端生成试题对年级和难度的校验逻辑，简化参数传递
- 修改服务端端口及API代理配置，保持一致性
- 调整相关数据库Mapper，支持批量查询和更新实际年级字段
- 修改错误信息字段命名，统一为msg
- 增删改代码注释与日志，提升容错性和可读性
