Applies an `edits[]` array to the stored `module` / `ui` / `styles` buckets. Each edit names a `bucket`, an exact `old_string` to match, and a `new_string` replacement. Requires `If-Match: "<N>"` carrying revision N from a fresh source response or ETag. A stale value returns 412 and surfaces the current ETag. Same auth as PUT.
