fix: Replace hardcoded paths with route/url helpers for subdirectory support

Files updated:
- layouts/knowledge-base.blade.php - Use url('/') for home link
- layouts/navigation.blade.php - Use url('/') for nav links
- layouts/guest.blade.php - Use url('/') for logo link
- Document.php - Use route() for wiki links
- DocumentLink.php - Use route() for URL attribute
- AuthenticatedSessionController.php - Use url('/') for redirects
- DocumentEditor.php - Use url('/') for redirect
- ProfileController.php - Use url('/') for redirect

This ensures the app works when deployed in a subdirectory
