refactor(orders): relax delivery address and date requirements for non-draft orders

- Updated order creation and update logic to allow saving orders without a delivery address or date, regardless of order status.
- Removed strict validation for delivery fields in the Delivery model, enabling more flexible order handling.
- Adjusted order form to reflect changes in required fields for delivery information.
