Work around iOS 27

On iPadOS 27, LumaBooth and LumaShare only print the first AirPrint job, then drop the rest. The developer who reported it on Apple's forum found a fix: create a new UIPrintInteractionController for each print job instead of reusing one. Link: developer.apple.com/forums/thread/843641. Please add this to LumaBooth and LumaShare. A lot of operators on AirPrint and WCM Plus are probably hitting this.
