Upscale a speaker headshot

A webhook starts it from a contact record in Airtable. It sets the image status to In Progress and sends the original headshot to the Topaz upscale model on Higgsfield, at 2x with face enhancement turned on.

The workflow waits and checks the request status until it reports completed or failed. When it completes, the upscaled image replaces the original_speaker_headshot attachment and the status changes to Done. Run it before background removal so the cutout starts from a sharper image.
