- Enhanced OrderForm to include recipient selection modes: customer, history, and new.
- Added AJAX endpoint to fetch recipient history for customers.
- Updated admin interface to manage recipients and display recipient information in order details.
- Refactored address handling to accommodate new recipient logic.
- Improved demo order creation to include random recipients.
