AWS powertools medium security documentation change
Summary
Updated documentation to support HTTP APIs, ALB, and Lambda Function URLs; added sections on catch-all routes, built-in error handlers, response serialization options, route prefixes, and streaming responses; updated runtime from nodejs22.x to nodejs24.x; added infrastructure examples for multiple services
Security assessment
Added security-relevant documentation for Lambda Function URL AuthType configuration warning ('AWS_IAM for added security beyond sample documentation'). This directly advises on securing access control. Also added CORS configuration examples which relate to security headers.
