When creating a new preparation display, it will now start with an empty backlog instead of showing all past orders. This ensures new displays only show orders created after they are set up, providing a cleaner and more organized workflow for restaurant staff.

Steps to reproduce:

- Create a preparation display

- Create orders to appear in it

- Create a new preparation display



Behavior:

- Past orders before the creation of the preparation display still appear.



Intended behaviour:

- New preparation display needs to be empty.
