Activatable UI component (#5184)

* Transfer most Instrument UI logic to a new component, ActivatableUIComponent

* Move more ActivatableUIComponent stuff to ECS

* ActivatableUI component ignore on client

* ActivatableUI: Get rid of component interfaces where possible

* Add in adminOnly attribute for activatable UIs

This is so that porting #4926 to this will be easier

* Transition Solar Control Computer to ActivatableUI

* Move communications console to ActivatableUI

* Move cargo console to ActivatableUI

* Move ID card console to ActivatableUI

* ActivatableUI: Make things more amiable to entity tests adding components weirdly

* ActivatableUI: Use handling or lack thereof of events properly

* ActivatableUI: component dependency issue resolution stuffs

* ActivatableUISystem: Fix #5258

* More fixes because master did stuffo

* Check for HandDeselectedEvent again because otherwise active-hand check doesn't work

* Move just a bit more code into the system, introduce a workaround for #5258

* Purge the player status detection stuff

* Oh and some obsolete stuff too
