/**
 * Integration Test: Sponsor Signup Use Case Orchestration
 *
 * Tests the orchestration logic of sponsor signup-related Use Cases:
 * - CreateSponsorUseCase: Creates a new sponsor account
 * - Validates that Use Cases correctly interact with their Ports (Repositories)
 * - Uses In-Memory adapters for fast, deterministic testing
 *
 * Focus: Business logic orchestration, NOT UI rendering
