Add a template by URL, or get a presigned upload URL

Adds a blank form to your organization's template library. The two request shapes match [POST /v1/files](https://docs.cloudraker.com/api/cloud-raker-api/files/create-file): - `{ url, name? }` — fetched over http(s) for you. - `{ name, mimeType }` — returns `uploadUrl` plus `uploadExpiresAt` (15 minutes); `PUT` the bytes with a `Content-Type` equal to the `mimeType` you sent. ```json { "url": "https://www.irs.gov/pub/irs-pdf/fw9.pdf", "name": "w9.pdf" } ``` <Note> Templates are deliberately never parsed or indexed — they are documents to be filled, not read. That is why a template reaches `ready` as soon as its bytes land, with no `processing` stage. Pass one to [fill](https://docs.cloudraker.com/api/cloud-raker-api/capabilities/fill) as `template: { "id": "…" }`. </Note> **Learn more:** [Form filling guide](https://docs.cloudraker.com/capabilities/fill)
