Removed unnecessary namespace in OrderBatchProcessor workflow and set a descriptive name for the workflow sequence. Updated the EF Core configuration in Program.cs to use SQLite with a specified connection string and ensure Order types are accessible in CSharp expressions.
Added a sequence with WriteLine activity to log processing of each order. Also, ensured the activity execution context properly sets its Tag property when a completion callback is provided.
Refactor the endpoint for listing workflow instances to use a more robust enum parsing method and improve validation. Update models to accept string collections for statuses and sub-statuses, which enables validating and parsing these enums directly within the endpoint.
The FetchProducts.cs and Product.cs files have been removed as they are no longer needed. Additionally, changes in the OrderBatchProcessor.cs and FetchOrders.cs reflect updates to order fetching logic to accommodate these removals.
