refactor: update MitmServerCard and MitmToolCard to use modalError instead of message for error handling

- Replaced message state with modalError in both components for better error management.
- Removed unused message display logic and adjusted action handling to improve clarity.
- Enhanced error handling in doAction and doDnsAction functions to ignore errors gracefully.
- Updated API call responses to streamline user feedback on actions.
