Open a redlining session on a Word document
Opens an editing session on a `.docx` file so you can rewrite it with tracked changes.
```json
{ "ttl": 86400 }
```
`ttl` is seconds until the session expires, from 60 to 604800 (one week); it defaults to the redlining service's own default. Nothing is stored back into your corpus until you call [flush](https://docs.cloudraker.com/api/cloud-raker-api/redline/flush-redline-session).
Only a Word document can be redlined. Everything else answers `422`.
