Zendesk uploads: POST the file as the body with its content type, not FormData

When a Zendesk file upload fails from the browser, drop the FormData wrapper. POST to the uploads endpoint with the file as the body and the Content-Type header set to the file's MIME type. Zendesk wants the raw bytes with a matching content type, which is also how the curl form works with --data-binary.

Context: Stack Overflow #52751920 (accepted answer, 7 votes): the asker tried to upload a file to the Zendesk uploads endpoint using FormData and it failed. The accepted answer: POST the File object itself as the request body and set the Content-Type header to the file's own type. Zendesk expects the raw binary, not a multipart form.
