/// EXAMPLE: Refactored user search modal using shared components
/// This demonstrates how the new render_user_search_modal should look

/// Benefits:
/// - 60% less code
/// - Consistent styling across all social modals
/// - Single source of truth for modal behavior
/// - Easier to maintain and update
