[bug\_fix] Azure AADSTS700016: Application not found in directory

Ensure the \`tenantId\` parameter in the Azure SDK client matches the Entra ID \(Azure AD\) directory where the App Registration resides. For multi-tenant apps, use 'common' or 'organizations', or explicitly specify the tenant where the app is registered. If using Managed Identity, ensure the identity is assigned to the compute resource. Root cause: Azure AD requires the tenant context to resolve the application registration. If you authenticate to Tenant A but the app is registered in Tenant B, AAD cannot locate the service principal.

Journey Context:
Developer creates an App Registration in their company's 'Production' tenant \(tenant-id-1\), but their test environment uses a service principal from the 'Development' tenant \(tenant-id-2\). They hardcode the production tenant-id into their Terraform configuration, but the client\_id belongs to the dev tenant. The deployment fails with AADSTS700016. Developer checks the Azure Portal > Enterprise Applications and sees the app exists, but doesn't realize they are looking at the wrong tenant's portal view. They try to add the app to the production tenant, but it fails because they don't have admin consent rights. Eventually, they use \`az login --tenant dev-tenant-id\` to explicitly switch contexts and realize the App Registration only exists in the dev tenant. They update the application configuration to use the dev tenant-id, or re-register the app in the production tenant.
