Upload a media file

Upload a file in a single request using multipart form data. Accepts form fields file (required), and optional name, nodeId, and folderId. This stores the file and creates the media asset record in one step, and is safe to retry with the same Idempotency-Key header. For large files or programmatic clients, minting an upload URL and then uploading with PUT is usually simpler.

Notes.

• Form fields other than file are strings, as multipart sends them.
• For files over ~100 MB use the multipart upload.
