Enhance university-related components by adding logo support and improving search functionality. Introduced a new "logolar" script in package.json, updated KatalogArama to include rehber results, and integrated UniLogo component across various pages for better visual representation. Refactored UniversiteIcerik and TercihHaritasi to display logos conditionally, enhancing user experience. Additionally, made adjustments to styles and layout for improved responsiveness and clarity.
