/**
* @fileoverview Quiz HTTP Controller - Clean Architecture Integration
* @version 1.0.0
* @since 2025-07-30
* @module QuizController
* @description HTTP controller integrating Clean Architecture handlers with Express routes
*
* @architecture
* Layer: Infrastructure (HTTP Adapter)
* Pattern: Controller Pattern + Adapter Pattern
* Dependencies: CreateQuizCommandHandler, GetQuizQueryHandler, DIContainer
*
* @relationships
* DEPENDS_ON:
* - CreateQuizCommandHandler (Application Layer)
* - GetQuizQueryHandler (Application Layer)
* - DIContainer (Infrastructure)
* USED_BY:
* - Express HTTP server
* - HTTP routing middleware
*
* @backwards_compatibility
* - Preserves exact same HTTP API interface
* - Maintains identical request/response formats
* - Supports all existing validation patterns
* - Adds Clean Architecture benefits (caching, validation, events)
*
* @contributors Claude Code Agent
* @testCoverage HTTP integration tests, Clean Architecture integration tests
