Created ValidateRequiredEnvironmentVariables function that validates all required environment variables before configuration loading. Validates required vars (JWT_SECRET, DATABASE_URL) in all environments, and additional production-specific validations (CORS_ALLOWED_ORIGINS, no wildcard, no DEBUG log level, RabbitMQ URL if enabled). Integrated validation at startup in NewConfig() to fail-fast if required variables are missing.",
