/**
 * Integration Test: Avatar Management Use Case Orchestration
 * 
 * Tests the orchestration logic of avatar-related Use Cases:
 * - GetAvatarUseCase: Retrieves driver avatar
 * - UploadAvatarUseCase: Uploads a new avatar for a driver
 * - UpdateAvatarUseCase: Updates an existing avatar for a driver
 * - DeleteAvatarUseCase: Deletes a driver's avatar
 * - GenerateAvatarFromPhotoUseCase: Generates an avatar from a photo
 * - 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
