/**
 * Integration Test: Sponsor League Detail Use Case Orchestration
 * 
 * Tests the orchestration logic of sponsor league detail-related Use Cases:
 * - GetLeagueDetailUseCase: Retrieves detailed league information
 * - GetLeagueStatisticsUseCase: Retrieves league statistics
 * - GetSponsorshipSlotsUseCase: Retrieves sponsorship slots information
 * - GetLeagueScheduleUseCase: Retrieves league schedule
 * - 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
