Don’t allow editing of users from other services

Browse Source 
Currently when you load the ‘edit user’ page (which has a URL like
`/service/<service_id>/users/<user_id>`) we check that:
- you belong to the service represented by `service_id`
- you have permission to edit users on this service

We don’t check that:
- the user represented by `user_id` belongs to this service

This means that if you could somehow determine another user’s `user_id`
(which I don’t think is possible if you don’t already have the manage
service permission for that service) then you could:
- edit their permissions on your service (weird, but wouldn’t have any
  effect)
- change their email address (bad)

This commit adds checks to return a `404` any time you’re looking at a
service and trying to do stuff to a user who doesn’t belong to that
service.

We can’t add this check to the API easily because there are still times
that we want to get/modify users outside the context of a service (eg
platform admin pages, or users who have no services).
