This page currently includes all notifications for all services, including
those sent using a test key. Stats on all other pages exclude test key usage,
though, which can lead to confusion for admins comparing numbers between
pages. Adding the option to toggle between including and excluding test key
usage on the platform admin page gives context for this difference, and allows
admins to see live usage of the platform as well as load associated with test
key usage.
* all current invocations of get_services now call get_active_services
EXCEPT for platform admin page (where we want to see inactive services
* cleaned up parameter names and unpacking (since *params is unhelpful)
* fixed incorrect kwarg name in conftest
Other than which services are live it’s also interesting to know what
services are getting created on Notify. So let’s put the newest ones at
the top of the page.
