Fix invisible vehicle parts list

[dseguin]

Summary

None

Purpose of change

Fixes #52447.
There was a small bug introduced by #51286, where only appliances were displayed in the vehicle parts installation list.

Describe the solution

Based on the original PR, appliances should probably only be installed via the construction menu. This change reverses visibility of items in the parts list, so that only non-appliance parts (aka basically all of them) are listed for installation in vehicles.

Describe alternatives you've considered

Allowing all parts including appliances to be installed in vehicles, although this would make the appliance unusable.

Testing

1. Spawn a car
2. 'e'xamine the car and try to install a part
3. Browse the non-invisible parts list

To make sure appliances still work:

1. Spawn a fridge item
2. Use the '*' construction menu to "place fridge"
3. 'e'xamine the placed fridge and plug the power cord into a nearby vehicle
4. Turn on the fridge
