Add lathe material ejection (#19218)

This completes PilgrimViis' (now closed) PR 16398. It addresses issue 10896, by allowing materials to be ejected from most lathes (except the ore processor and sheet-meister 2000)

* - Refinements to the material ejection UI
- Made the lathe UI default to a slightly larger size
- Fixed an offset issue with the label of the item currently being printed in the build queue UI

* Allow the materiel reclamation UI to pop if there is material left in the lathe, but not enough to print any sheets
