Edit a generated image with a prompt

A button on an image record in Airtable calls the webhook. The workflow sets the edit status to AI Writing, then sends the record's edit prompt and its current image to the Fal.ai image edit model linked on the record.

It waits and checks the job until Fal.ai reports it complete, downloads the result and replaces the record's attachment with the edited image, setting the status to AI Complete. If the job fails the record is marked Error. The image cost is logged to an AI usage table with the brand and event it belongs to.
