feat(admin): 实现用户管理的增删改查功能

- 新增用户添加接口，支持数据库中创建用户
- 实现用户编辑接口，允许更新用户信息
- 添加用户删除接口，支持从数据库删除用户
- 修改路由配置，新增用户编辑和删除的GET请求路径
- 使用gorm完成用户数据的增删改查操作
- 初始化数据库连接，自动迁移User表结构
- 新增User和Article模型定义及对应的表名函数
- 在main.go中添加session中间件支持
- defaultController中实现基于session的用户名保存与读取
- 添加go.mod依赖，包含gorm与gin-contrib/sessions相关包
