/**
 * View Data Layer Tests - Admin Functionality
 * 
 * This test file will cover the view data layer for admin functionality.
 * 
 * The view data layer is responsible for:
 * - DTO → UI model mapping
 * - Formatting, sorting, and grouping
 * - Derived fields and defaults
 * - UI-specific semantics
 * 
 * This layer isolates the UI from API churn by providing a stable interface
 * between the API layer and the presentation layer.
 * 
 * Test coverage will include:
 * - Admin dashboard data transformation
 * - User management view models
 * - Admin-specific formatting and validation
 * - Derived fields for admin UI components
 * - Default values and fallbacks for admin views
