SkyratBot dbd9dfa66b [MIRROR] All vehicles can no longer cross Force Fields [MDB IGNORE] (#24841) 
* All vehicles can no longer cross Force Fields (#79553)

## About The Pull Request

Fixes #78625

The check only applied to mecha vehicles, when in reality there
shouldn't be any vehicle that can freely transverse containment fields,
since that vehicle will have a mob in it, which itself shouldn't be
allowed to traverse containment fields.
## Why It's Good For The Game

Makes behavior more consistent and expectable.
## Changelog
🆑
fix: All vehicles (such as VIMs operated by a mouse or a lizard) will no
longer be able to phase through containment fields.
/🆑

* All vehicles can no longer cross Force Fields
