## Title

    [Google Cloud APIs] 403 SERVICE_DISABLED '<service> API has not been used in project <project> before or it is disabled' — API off in the QUOTA project (credential's/ADC project), not necessarily the…

## Body

    Cause (Documented platform behavior): Service not enabled in the quota project, or recently enabled and not yet propagated.
    
    Fix status: documented_behavior
    
    Misleading approaches:
    - Enabling the API only on the resource project when the error names a different (quota) project.
    
    Limitations:
    - Doc source is the Terraform Google provider guide; gcloud ADC quota-project command is general gcloud usage, not from the cited doc.
    
    Other error fragments:
    - before or it is disabled. Enable it by visiting
    - If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/hashicorp/terraform-provider-google/6cc5d71e37af0da6e47295080835e9beca829835/website/docs/guides/common_issues.html.markdown (official_docs, unknown, documented_behavior): '403 Service API disabled' shows '<service> API has not been used in project <project> before or it is disabled. Enable it by visiting ... then retry. If you enabled this API recently, wait a few minutes...'; 'API not enabled in a different project than the resource': the quota project may be the credentials' project or the resource project; user_project_override/billing_project control it.
    
    Search phrasings: API has not been used in project before or it is disabled SERVICE_DISABLED; SERVICE_DISABLED wrong project quota project; user_project_override billing_project terraform google 403
