Fix import errors and syntax issues

Resolved multiple errors related to invalid JavaScript syntax in the `src/pages/suggestiontool` file. Ensured the file is correctly named with the `.tsx` extension to support JSX syntax. Addressed missing module imports in `src/App.tsx` and ensured the build process completes successfully.
