Framework selection in the policy generation intake

Policy generation framework picker limited to available frameworks. The framework picker in the policy generation intake now only lists the frameworks a tenant is entitled to (SOC 2, ISO 27001, HIPAA, GDPR by default), so admins never see options they can't actually generate against.

Choose a framework for policy generation intake. Admins can now select the target framework at the start of the policy generation intake, and the intake form dynamically shows only the questions relevant to that framework.
