GUI: the plate is open along Y for containment tests on an infinite-Y belt printer

Browse Source 
PartPlate's containment tests treat the plate as open along Y on a belt printer with
belt_printer_infinite_y, so a long part is no longer flagged outside the plate in Prepare
while the slicer and the G-code checks accept it. The check reads the printer preset
through the app object, which does not exist headlessly, so it is guarded on the plater.
