🔧 fix(endpoints.py): remove unused import 'process_graph_cached' and replace it with 'process_graph_cached_worker' for processing graph data asynchronously

🔧 fix(endpoints.py): add error handling for processing tweaks and log the error message
✨ feat(endpoints.py): use 'process_graph_cached_worker' to process graph data asynchronously and return the result in 'ProcessResponse'
