[MIRROR] Adds craftable surgery trays. [MDB IGNORE] (#23790)

* Adds craftable surgery trays. (#78364)

## About The Pull Request

Surgery trays can now be crafted in the crafting menu for two rods and
one silver, while having a screwdriver. (Same cost as a table.)
Out of necessity, the preloaded variants of surgery trays have been
re-pathed to a full subtype, though maps have already been updated to
use the preloaded variant.

The morgue tray and the (new!) advanced trays have been re-pathed to
`.../full/morgue` and `.../full/advanced`, respectively

Additionally, surgery trays can now be deconstructed by secondary click
with a screwdriver. Woo!

## Why It's Good For The Game

If you want more surgery trays, build 'em!
If you want less surgery trays, unbuild 'em!
