Add 'Scan DNA' function to medical scanner (#1783)

* Add art assets for cloning

* Added a 'Scan DNA' button to the medical scanner

* Made the UI update unconditional for the medical scanner until checks for power changes are in place

* Update Medical scanner to reflect powered status and fix #1774

* added a 'scan dna' button the the medical scanner that will add the contained bodies Uid to a list in CloningSystem, fixed an issue with the menu not populating if the scanner starts in an unpowered state

* Add disabling logic to 'Scan DNA' button on medical scanner

* Removed un-used libraries

* changed scan dna button to Scan and Save DNA
