/**
 * Integration Test: Team Membership Use Case Orchestration
 * 
 * Tests the orchestration logic of team membership-related Use Cases:
 * - JoinTeamUseCase: Allows driver to request to join a team
 * - CancelJoinRequestUseCase: Allows driver to cancel join request
 * - ApproveJoinRequestUseCase: Admin approves join request
 * - RejectJoinRequestUseCase: Admin rejects join request
 * - 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
