feat(enlish-service): 新增自动判卷功能及学生单词记忆管理模块

- 支持数据库多语句查询，修改数据源连接配置增加allowMultiQueries参数
- 添加定时任务AutoJudgeExamWordsTask，实现每5秒自动触发判卷
- 增加ExamWordsJudge接口及其实现类ExamWordsJudgeImpl，完成考试判卷逻辑
- 新增多张数据库映射文件及对应Mapper，如ExamWordsDOMapper、ExamWordsJudgeResultDOMapper、StudentExamWordsDOMapper和WordMasteryLogDOMapper，支持相关数据操作
- 扩展PngUtil工具类，支持从答题卡图片中解析学生考试信息和识别未记忆单词
- 修改数据库表结构映射，新增word_mastery_log表和相关字段，管理学生单词记忆强度及复习次数
- 配置@EnableScheduling以启用定时任务调度功能
- 增加测试用例包括ExamWordsJudgeTest和WordMasteryLogInsertTest，验证判卷和学生单词记忆初始化功能
- 重命名测试类TestInsert为TestVocabularyBankInsert，提升代码语义清晰度
