Proj i08/fix terraform region

[georges-nasrallah]

Summary

Fix Azure region and restore OIDC environment binding so the cd-dev workflow can provision the AKS cluster.

Closes #PROJ-I08

---

Motivation & Context

The CD pipeline failed because (1) the Azure subscription policy disallows westeurope, and (2) the OIDC federated credential subject expects environment:dev but the workflow was missing that setting.

---

Changes

• Switch Terraform default region from westeurope to germanywestcentral
• Restore environment: dev to the cd-dev workflow job so the OIDC subject matches the federated credential

---

Steps for Testing

1. Merge to main and trigger CD - Dev (AKS) workflow
2. Verify Azure login, Terraform apply, and Ansible deploy all pass
