Optimize mask handling and shape mask UX for output area

Browse Source 
Replaces full-canvas mask operations with getMaskForOutputArea() for significant performance improvements when processing masks for the output area. Refines shape mask removal and application logic to ensure correct mask state when changing expansion values or custom shapes, including auto-removal and re-application of masks. Adds throttling to shape preview rendering for better UI responsiveness. Improves mask removal to eliminate antialiasing artifacts and updates SAM mask integration to use correct output area positioning.
