Download a job artifact's bytes (static_ad creative images)

Job results do not list artifacts: take the creative id from creatives[].id in the ad.json file the job writes to its chat workspace (see the files endpoints), and pass the chat the job was submitted under. Other families return 404 artifact_not_found. Never metered.
