Add sorting functionality to Search GUI for improved result management

This commit enhances the SearchGUI class by introducing sorting capabilities for search results. Users can now sort results by 'Person' and 'Photo path' columns, with visual indicators for sort direction. The sorting state is maintained, allowing for toggling between ascending and descending orders. Additionally, the default sorting is set to 'Person' when results are first loaded, improving the overall user experience in navigating search results.
