/**
 * Integration Test: Sponsor Dashboard Use Case Orchestration
 * 
 * Tests the orchestration logic of sponsor dashboard-related Use Cases:
 * - GetDashboardOverviewUseCase: Retrieves dashboard overview
 * - GetDashboardMetricsUseCase: Retrieves dashboard metrics
 * - GetRecentActivityUseCase: Retrieves recent activity
 * - GetPendingActionsUseCase: Retrieves pending actions
 * - 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
