Predicted internals (#33800)

* Predicted gas pumps

I wanted to try out atmos and first thing I found.

* a

* Atmos device prediction

- Canisters
- Tanks
- Internals

AirMixes aren't predicted so nothing on that front but all the UIs should be a lot closer.

* Remove details range

* Gas tank prediction

* Even more sweeping changes

* Alerts

* rehg

* Popup fix

* Fix merge conflicts

* Fix

* Review
