Subject: [PATCH] Create FoodService.cs

Description:

I introduced the FoodService class responsible for handling business logic related to food items. This class encapsulates the operations for retrieving food items, creating pagination metadata, and building links. It plays a pivotal role in keeping the controller clean and focused on handling HTTP requests while ensuring separation of concerns.
