ci: fail CI if everyvoice -h imports shared_types, that is slow

Let's just be a bit more agressive blocking expensive imports: the easiest way to let expensive imports slip into everyvoice -h is by accidentally causing it to import everyvoice.config.shared_types, directly or indirectly. So let's explicitly look for the and reject a commit in CI if it causes this.
