/**
 * Integration Test: League Media Management Use Case Orchestration
 * 
 * Tests the orchestration logic of league media-related Use Cases:
 * - GetLeagueMediaUseCase: Retrieves league covers and logos
 * - UploadLeagueCoverUseCase: Uploads a new league cover
 * - UploadLeagueLogoUseCase: Uploads a new league logo
 * - UpdateLeagueCoverUseCase: Updates an existing league cover
 * - UpdateLeagueLogoUseCase: Updates an existing league logo
 * - DeleteLeagueCoverUseCase: Deletes a league cover
 * - DeleteLeagueLogoUseCase: Deletes a league logo
 * - SetLeagueMediaFeaturedUseCase: Sets league media as featured
 * - 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
