Subject: [PATCH] fix(tools): make image_understand image_url optional and
 remove unused operation variable

Change image_url from required to optional in both operation_tool.py and
tool_service.py for image_understand operation, avoiding parameter validation
conflict with uploaded_files priority logic.
Remove unused operation variable from OpenClawTool.execute().
