Merges the progress fields into the existing transfer record. If no record exists yet (race: progress arrives before the initial upsert), a minimal placeholder is created so the UI can render immediately.

      bytesDone: number;
      bytesTotal?: number;
      partsDone: number;
      partsTotal: number;
      requestId: string;
