Add checks for various complex interactions (#37246)

* Prevent toggling radiation collectors

* Prevent resisting locks

* Prevent unbuckling others, early exit before doafter

* Prevent camera and camera router setup

* Prevent rotating and flipping

* Also prevent adding the unbuckle verb.

* Revert ResistLocker changes

* Prevent emitter tampering

* Also prevent lock verb

* Prevent toggling welders

* Prevent gun open/close bolt, rack and switch mode

* Prevent toggling stun batons
