Subject: [PATCH] feat: update product service to support in-stock filtering
 and enhance top-selling product retrieval

- Modified `GetTopSellingAsync` methods in `ProductService` and `DiscountProductService` to include an optional `inStock` parameter for filtering products based on availability.
- Introduced a constant for the top product count in `Index.razor.cs` to improve maintainability and readability.
- Updated the product retrieval logic in `Index.razor.cs` to utilize the new in-stock filtering feature.

These changes enhance the product listing functionality by allowing users to view only in-stock top-selling products, improving the overall shopping experience.
