Issue description
There is two paused buildings. One has the update paused, one not. You cannot see it here (only in the building's update dialog).
The Pause Tool affects the update, not the building production/ transport function. I think that is right, but again, the issue is the missing visual indication.

Expected behavior
The visualisation concept is failing here (needs to be extended/ reworked) ...
Buildings/ transports to be updated do need both kinds of pause. However, they are not white ghosts and do not have colored scaffoldings while waiting for the update materials.
Reproduction steps
Pause production of a buillding and mark it for update.
