Create Envelope POST

Create a new envelope. Returns a presigned POST upload configuration for uploading the PDF file directly to S3. After creating the envelope, use the returned `upload.url` and `upload.fields` to upload your PDF via a multipart form `POST` to S3. S3 enforces a 10MB file size limit at upload time. **File Constraints:** - Only PDF files are supported - Max file size: 10MB (enforced by S3) **Organization Context:** If the API key was created in an organization workspace, the envelope is automatically associated with that organization and credits are deducted from the organization's wallet.

Generate Upload URL POST

Generate a new presigned upload URL for a draft envelope. Useful if the original URL has expired.
