Initialize image/video upload to selected test account library. Returns signed receipt for chunk upload/finalization. No arbitrary upload host accepted.

> **Note** Advertising API Development tier. Test-account writes only; Standard access is not yet approved.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
