Ticket: QOV-2504


Summary by cubic

Removes the exportSecrets query parameter from the openapi.yaml Terraform export endpoint, aligning the spec with the exporter's new secret-redaction behavior.

The endpoint documentation now states that secret values are never included in exports: service secrets are preserved as empty input variables marked Redacted, while cloud, Git, registry, and cluster credentials must be supplied through input variables without defaults.
