Order templates are currently stored in mod-configuration, but they're being moved to the orders app. As such, the various places that save/retrieve/manage order templates (settings as well as order/poLine forms) need to be updated.
NOTE: the new API will return json not a string.
- update dependency/permissions (if needed)
- order templates section in settings use the order templates API in mod-orders
- create/edit/details order and poLine views use the order templates API in mod-orders
- tests are updated
