feat(display-attendies): save in db

The waiting list is now saved in the db because before doing so the wating list was calculated on each request on the ui AFTER getting only the attendies that allowed the display which leads to false results. And it is now possible to get if an attendie is on the waiting list even if we only want do get one attendie via the API
