Subject: [PATCH] Disposal Units tag their contents + UI comp state (#45613)

* commit

* also flipped

* oops

* fuck it added to the UI

* fix micro annoyance

* Unify components also doesn't work yet

* reuse the existing UI also clean up the UI also applying state headache

* cheat code

* flippy

* More interface changes

* yaml ;p

* private tagger

* betterer tagger

* private unit window

* limit tagger window

* access blocked

* typo

* validate
