功能(auth)：实现用户注册并分配默认角色

- 添加AppConfig类以启用事务管理
- 在application.yaml中配置默认角色代码
- 在AuthServiceImpl中注入RoleMapper和defRoleCode
- 在注册过程中为新用户分配默认角色
- 添加用户注册和登录事件的日志记录
- 在登录过程中处理异常并进行适当的错误日志记录
- 创建用户、角色、权限及关联关系的数据库表
- 添加用户角色实体类和用户-角色关系映射器
- 实现用户角色服务以管理用户角色分配
- 添加通过SetUserRoleRequest设置用户角色的API端点
- 更新用户实体类并添加适当的字段和注解
- 实现包含角色信息的用户信息查询方法
- 将用户转换逻辑重构为可复用方法
- 为SetUserRoleRequest DTO添加校验约束}```
