访问Articles/1/接口时报错：get()方法收到'id'参数的多个传值

• 核心错误出在ArticleDetails类的get方法参数定义不符合DRF规范：
  DRF的APIView子类中，所有处理HTTP请求的方法（get/post/put/delete等），参数固定顺序为 self -> 请求对象request -> 路由捕获的路径参数。你当前的get方法定义为def get(self, id):，系统调用时会依次传入self、request对象、路由提取的id值，此时第二个参数id会先接收request对象，第三个传入的路径id又会赋值给id参数，直接触发「参数id收到多个值」的类型错误。
• 附加隐藏问题：get_objects方法查询不到数据时直接返回Response对象，后续序列化操作会因为传入非模型实例报错。

1. 补全get方法的request参数，和其他put/delete方法保持参数顺序一致
2. 修改get_objects的错误处理逻辑，查询失败时抛出404异常而非返回响应对象
3. 确认路由配置中路径参数名和方法参数名一致，参考路由规则：path('Articles/<int:id>/', ArticleDetails.as_view())
