Refactor Stripe payment handling and order status

Refactored Stripe payment integration to use a dedicated Stripe model for session data, updating the PaymentSerializer accordingly. Renamed Order.Status to Order.OrderStatus for clarity. Updated configuration app to ensure SiteConfiguration singleton is created post-migration. Removed obsolete seed_app_config command from docker-compose. Adjusted frontend API generated files and moved orval config.
