Migrate Lathe Material Ejection Code to MaterialStorage (#23199)

* SS14-23184 Migrate Lathe Material Ejection Code to MaterialStorage

The lathe material ejection code acts as a do-nothing
man-in-the-middle system that does work that would be
reasonable for any MaterialStorage-using machine to
use. This has been fixed by migrating the ejection
code to MaterialStorage, allowing anything that uses
the system to eject mats it is storing.

* Fix some YAML references. Science!!
