/**
 * Integration Test: League Standings Use Case Orchestration
 * 
 * Tests the orchestration logic of league standings-related Use Cases:
 * - GetLeagueStandingsUseCase: Retrieves championship standings with driver statistics
 * - 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
