fix: Use slug for Document route model binding

- Add getRouteKeyName() to return 'slug' for Document model
- Add resolveRouteBinding() to support both slug and ID lookups
- Update QuickSwitcher to use slug instead of ID
- Update quick-switcher blade to use slug in routes

This ensures URLs use readable slugs (e.g., /documents/home)
while maintaining backwards compatibility with ID-based URLs
