Submit to a form

Webhooks stay the primary way to receive responses; this is how you recover the ones you missed. Pass `since` on deploy, or after any outage, and backfill everything your endpoint did not acknowledge. `answers` is the same object the `form.submitted` webhook carries, so a single parser handles both paths. Newest first, cursor paginated. Submissions marked as spam are withheld unless you ask for them. **`document` is present only when the form has a template connected**, and its absence means no document will ever exist for that submission. When it is present, `status` runs `pending` → `processing` → `completed` (with a `url`) or `failed` (with an `error`). `pending` means the background job has not created the render yet, which is normal for the first few seconds after a submission — do not read it, or a missing `render_id`, as a failure.
