- Introduced a new endpoint `/preview-order-no` to generate order numbers based on registered numbering rules without incrementing the sequence.
- Implemented the `previewOrderNo` function in the `outsourcePurchaseController` to handle the logic for generating the preview order number.
- Updated the `outsourcePurchaseRoutes` to include the new route for previewing order numbers.
- Enhanced the `RegistrationModal` component to automatically fill the order number input with the preview value when the modal opens.
- Added a new API function `previewOrderNo` in the frontend to call the backend endpoint.
