Mini Fridges now have a grimy subtype, can go over tables, and start off anchored. (#76517)

## About The Pull Request

/obj/structure/closet/mini_fridge is now a clean nice one, which only
spawns beverages and does not have that cockroach reference in the
description, and starts off anchored. now
/obj/structure/closet/mini_fridge/grimy works like the old mini-fridge,
with syndicake, moldy bread, and now the chance of an ACTUAL cockroach.
I've replaced them on maps according to each one's needs, So, as an
example, Northstar gets a regular one (it var edited it before) while
tram maints get the grimy subtype.
mini-fridges now can properly go over tables, so you don't have to
deconstruct said table to put it on top again.
## Why It's Good For The Game

I've found the need for a nice subtype while doing a ruin, and so has a
few other mappers apparently, as northstar had a var edited variant. The
fact that it couldn't go over tables and started off unanchored was
annoying on tram and icebox, where it is present on the kitchen and you
could easily push it to the ground and suffer.
## Changelog
