Deny non-active registrars access to non-free EPP commands

Registrars that are PENDING or SUSPENDED should not have access to
EPP commands that cost money, as in either case it's not likely we'd
actually be able to get payment from said registrar. For this reason
we already prevented access to the domain create flow for non-active
registrars. This commit extends that to other commands that cost
money, including renewals, restores, and transfer requests.

Note that implicit autorenews will still occur for suspended
registrars, as in our point-in-time data model there's no good way
to prevent them. So when a registrar is suspended for non-payment,
the game plan is to get all of their domains transferred out to a
registrar that will pay as soon as possible.
