/**
 * Integration Test: Track Image Management Use Case Orchestration
 * 
 * Tests the orchestration logic of track image-related Use Cases:
 * - GetTrackImagesUseCase: Retrieves track images
 * - UploadTrackImageUseCase: Uploads a new track image
 * - UpdateTrackImageUseCase: Updates an existing track image
 * - DeleteTrackImageUseCase: Deletes a track image
 * - SetTrackFeaturedUseCase: Sets track 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
