Test a moderation policy with mock scores without saving results

## Request body

- object: Request body for content moderation. Send user-generated content (text, image URL, or video URL) and a policy ID to get an allow/flag/block decision.
  - `content` string, required: The user-generated content to moderate. For text, send the raw string. For images, send a URL or base64 data URI. For video, send a URL.
  - `policyId` string, required: ID of the moderation policy to evaluate against. Use "default" if you have not created a custom policy.
  - `contentType` 'text' | 'image' | 'video': Type of content. Determines which AI models are used for scoring.
