/**
 * Integration Test: Drivers List Use Case Orchestration
 * 
 * Tests the orchestration logic of drivers list-related Use Cases:
 * - GetDriversListUseCase: Retrieves list of drivers with search, filter, sort, pagination
 * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
 * - Uses In-Memory adapters for fast, deterministic testing
 * 
 * Focus: Business logic orchestration, NOT UI rendering
