Add Gin theme as default admin theme for Open Intranet

Context

Open Intranet currently uses the default Drupal administrative interface, which provides basic functionality but lacks the modern, user-friendly experience that content managers and administrators need for daily operations. The Gin theme is a modern, accessible admin theme that significantly improves the administrative experience with better usability, cleaner interface, and enhanced productivity features.
