Orders

## How the collection site is chosen

[Create an order](https://api.docs.originone.ai/api-reference/orders/create.md#choosing-a-collection-site) now explains how `clinicSelectionMode` picks the collection site, which `schedulingOption` each mode works with, and what the order looks like after creation in each mode. The API itself hasn't changed.
