/**
 * Integration Test: Onboarding Personal Information Use Case Orchestration
 * 
 * Tests the orchestration logic of personal information-related Use Cases:
 * - ValidatePersonalInfoUseCase: Validates personal information
 * - SavePersonalInfoUseCase: Saves personal information to repository
 * - UpdatePersonalInfoUseCase: Updates existing personal information
 * - GetPersonalInfoUseCase: Retrieves personal information
 * 
 * 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
