feat: enhance icon loading robustness

Improved the `icon` function to handle attribute errors gracefully by falling back to an alternative reading method. This change addresses potential situations where the `file.response.file` attribute does not exist, ensuring icons are consistently loaded without causing runtime errors. The fallback method, `file.response.read()`, provides a reliable alternative for retrieving SVG files, thus enhancing the application's resilience and user experience.
