Commits a file that was uploaded directly to S3 via `POST /knowledgebase/get-presigned-url`, registers it as a knowledge-base item, and triggers async processing. **Note**: The path includes `compelete` (sic) — that's the actual route name on the platform. Don't fix the spelling in your client; it's a stable URL.
