Delete a group of renders — the same filters GET …/renders takes.

At least one filter is required. A bare DELETE …/renders would mean "every creative there is", which is not something anyone should be able to ask for by forgetting a query string.

Deleting a render is not destroying anything irreplaceable: a render is a pure function of its template version, the product and its assets, so the next run — or the next "Render this product" — makes it again. See services.creatives.delete_renders for why the file goes after the row.
