[TM-ONLY][DNM] Attempts to remove all instances where a list is accessed with a '?' (#5932)

* I hate TGUI even if its better than what we had before

* this is why linters exist

* you need to be a Head or the Warden to get items

* does this please you linter?

* foundation

* basic interactions

* yea I can spell okay?

* linters please leave me alone

* begone debug code

* if you are dead, no interacting

* linters leave me alone

* linters are stealing my soul

* forgot to do this

* sound framework, probably wont work though

* max length, and interaction cooldowns

* message can now be a list and minor code improve

* I am a slave and linters are my master

* fix improper static reference

* add json loading/saving functionality

* default for message is now a list

* jsonize def interactions; implement requirements

* bad

* bug fix; CtrlShiftClick to interact

* minor qol fix

* fix CtrlShiftClick and remove debug code

* haha docker has security measures

* this was painful

* why are you in this branch

* begone

* bruh

* begone
