Upload a new asset file to Frontify programmatically using the GraphQL `uploadFile` mutation flow

Steps

1. Call the `uploadFile` GraphQL mutation (requires the `basic:write` scope) to create a temporary file upload and receive a temporary file ID plus presigned URL(s) for uploading binary data in parts
2. Upload the file's binary content directly to the returned presigned URL(s); for files under roughly 15MB this is a single part, while larger files are split into multiple parts up to a few GB each
3. Once all parts are uploaded, use the temporary file ID in a follow-up mutation to permanently attach it to a target type such as Asset, Attachment, or Revision
4. Note that the temporary file ID can only be redeemed once — plan the follow-up linking mutation to run immediately after upload completion rather than caching the ID for later reuse
5. Verify the resulting Asset/Attachment appears correctly in the target Frontify library or project via a follow-up query
