This commit enables the Cloud Run deployment method in
the `Project :: Infra :: Google Cloud` section.

Minimal frontend changes that rename props and flip the
disabled switch.

Backend changes introduces a service to enable the underlying
Google Cloud services via their API. Then of course there's a
controller method that responds to the user clicking the now
enabled button.
