Companion service to the Presigned URL API that tracks file upload progress, stores metadata (file size, type, upload timestamp), and confirms successful uploads to the requesting application. The Dashboard polls this service to show upload progress bars and confirm document receipt. If down, uploads still succeed (files reach S3) but the frontend shows perpetual "uploading" spinners and cannot confirm completion to the user.
