Add concurrency locks and detailed logging to canvas processing

Browse Source 
Introduces concurrency locks in Python and JavaScript to prevent simultaneous processing and saving operations in canvas-related workflows. Adds extensive logging throughout the canvas image processing, saving, and matting routines to aid debugging and trace execution flow. Also improves error handling and state management in both backend and frontend code.
