bug: terraform validate fails in elasticache.tf due to invalid aws_default_vpc data source

[Panacota96]

Summary

erraform validate fails before any plan/apply work because �lasticache.tf declares data "aws_default_vpc" "default", which is not a supported AWS provider data source.

Evidence

• File: phishing-platform-infra/terraform/elasticache.tf:3
• Command: erraform -chdir=phishing-platform-infra/terraform validate
• Error: The provider hashicorp/aws does not support data source "aws_default_vpc".

Impact

• Infrastructure validation is broken.
• CI/CD and local Terraform workflows cannot trust the IaC baseline.

Expected outcome

Replace the invalid VPC lookup pattern with a supported resource/data strategy and keep erraform validate green.
