feat(api): 菜谱接口使用 redis streams TUN-124

为应用程序添加了从 URL 添加食谱的功能，允许用户通过提供来源和URL来添加食谱。如果成功添加，将会返回成功消息，否则将会返回错误消息。

该功能的实现包括以下步骤：
- 在`app.py`文件中添加了`add_recipe_from_url`函数，用于处理从URL添加食谱的逻辑。
- 在`/add_recipe`路由中，根据请求中的来源和URL调用`add_recipe_from_url`函数来添加食谱。
- 如果添加成功，将会返回成功消息和状态码200；否则，将会返回错误消息和适当的状态码。

该功能的实现还包括对Redis的连接和消费者组的创建，以及从Redis Stream中读取未消费的消息并进行处理。
