Pull Request Overview

This PR adds support for Application Load Balancer (ALB) origins to the CloudFront WAF module, allowing users to specify an ALB ARN instead of a domain name for the origin configuration.

• Introduces origin_alb_arn variable to accept ALB ARN as an alternative to domain-based origins
• Updates origin domain resolution logic to use ALB DNS name when ALB ARN is provided
• Adds certificate attachment to ALB listener for proper TLS negotiation with CloudFront
