Combo products are now shown with a clearer parent-child layout on preparation displays, making it easier for staff to see which items belong together. Related combo lines also stay synchronized when order changes are handled, reducing confusion and helping kitchen or preparation teams process orders consistently.

- Indent child combo product in prepatration display
- Implemented synchronization between combo lines and parent orderlines for consistent handling of the `skip_change` state across all related lines.
- Added a parent-child connection for orderlines in preparation display so that we can check the combo parent only to send the combo-lines to the next change and vice versa.
