/**
 * Integration Test: Sponsor Logo Management Use Case Orchestration
 * 
 * Tests the orchestration logic of sponsor logo-related Use Cases:
 * - GetSponsorLogosUseCase: Retrieves sponsor logos
 * - UploadSponsorLogoUseCase: Uploads a new sponsor logo
 * - UpdateSponsorLogoUseCase: Updates an existing sponsor logo
 * - DeleteSponsorLogoUseCase: Deletes a sponsor logo
 * - SetSponsorFeaturedUseCase: Sets sponsor 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
