process not running alert can be shadowed

### Describe the bug

Encountered this when I went to help a new user drive on NMS Passat by taking it out of dashcam. They went straight into "LKAS Fault: Restart the car to engage". The immediate cause was PEBCAK, specifically a failure to pull my local dev environment to current, but the displayed alert led me astray when troubleshooting.

It looks like we properly raised `processNotRunning`, but unfortunately `steerUnavailable` displayed on top of it. The controls crash should be displayed first, both due to severity and due to the fact it will cause several other faults from the car.
