修复：解决管理员token访问用户接口401问题

- 修改AuthInterceptor使用JwtUtil直接验证token，支持管理员和普通用户
- 移除AuthService的Redis检查依赖，使用JWT本身的验证机制
- 添加用户类型(userType)信息到请求属性中
- 完善用户上下文设置和清理逻辑
- 添加详细的调试日志

修复内容：
1. 统一token验证：管理员和普通用户token都通过JwtUtil验证
2. 移除权限限制：当前阶段不限制token类型对接口的访问权限
3. 保留扩展性：userType字段为后期权限控制预留配置
4. 验证通过：管理员登录后可以正常访问所有接口
