- Implemented CRUD views for managing order statuses
- Created OrderStatusService with status transitions and business logic hooks
- Updated Order model to use ForeignKey to OrderStatus
- Added is_returned flag for tracking returned orders
- Updated filters to work with new OrderStatus model
- Created management command for status initialization
- Added HTML templates for status list, form, and confirmation
- Fixed views.py to use OrderStatus instead of removed STATUS_CHOICES
