chore(iac): remove unused destroy pipeline and script

Removed the unused `.azuredevops/pipelines/destroy.yml` pipeline file and the corresponding `.github/workflows/stage-4-destroy.yaml` GitHub Actions workflow. Updated the `stage-4-deploy.yaml` workflow to dynamically use the ADO project name. Also, removed the `terraform-destroy` target from the `terraform.mk` Makefile.
