Allows nuke core containers to be broken open (#16570)

* Allows nuke core containers to be broken open

* Apply suggestions from code review

Co-authored-by: Farie82 <farie82@users.noreply.github.com>

* Improves unload, removes duplicate, better logging, changes name on cracking open

* Update code/game/objects/items/theft_items.dm

Co-authored-by: dearmochi <1496804+dearmochi@users.noreply.github.com>

* Some of sabres stuff

Co-authored-by: SabreML <57483089+SabreML@users.noreply.github.com>

* Fixes engineers / atmos techs getting objective, boldnotice

* Testing to figure out why this is conflicted
