Set Promo Thumbnail

POST 
/api/share/promo-video/thumbnail

Set a custom poster image for the sharer's promo video of one item_type.

The image is stored on the public uploads bucket via UploadService and served at /api/upload/{tenant}/image/{file} (a public-exempt path), so it works cross-origin on the share page without Bunny's hotlink protection. The stored URL is absolute (API_BASE_URL + path) since the same value is read by the public votel.ai/share page. Replacing an existing custom thumbnail best-effort deletes the old image.
