- Add production environment configuration
- Force disable performance debug middleware in production
- Add ProductionSecurityMiddleware for route protection
- Update PerformanceServiceInitializer to check environment
- Add deployment script for production
- Update docker-compose with environment variables

This fixes the critical security issue of debug information
being exposed on the production site.
