/**
 * Integration Test: Dashboard Error Handling
 * 
 * Tests error handling and edge cases at the Use Case level:
 * - Repository errors (driver not found, data access errors)
 * - Validation errors (invalid driver ID, invalid parameters)
 * - Business logic errors (permission denied, data inconsistencies)
 * 
 * Focus: Error orchestration and handling, NOT UI error messages
