This can happen if you click a link for a service you don’t have access
to. We shouldn’t show the back to service link in this case because:
- you shouldn’t be able to find out the service’s name from just knowing
the link
- if you click the link you only get a `403` anyway
We already have a pattern for navigation folders and searching for
templates – let’s use it for the copy page too. And I reckon we can
represent services as folders if the user has multiple services they
could copy a template from.
This commit is the first step to disentangling the models from the API
clients. With the models in the same folder as the API clients it makes
it hard to import the API clients within the model without getting a
circular import.
After this commit the user API clients still has this problem, but at
least the service API client doesn’t.
