Morgue tray adjacency fixes

[SECBATON-GRIFFON]

[bugfix][oversight][sanity]

What this does

Closes #34551.
Closes #35645.
compresses the crematorium and its tray down to a subtype of the morgue stuff for less copied code and so the fix works with both.

How it was tested

putting stuff in and out of morgues and crematoriums, cremating the insides, using a subspace tunneller on the trays and cremators.

Changelog

🆑

• bugfix: Morgue and crematorium trays can no longer be closed to teleport their contents back to the morgue or crematorium if not adjacent.
• bugfix: Morgues and crematoriums no longer take the crystal and matter bin from the subspace tunneller its tray was in.

Alternative solution: You close this and we all just act like it was merged so fun survives.
Have you ever put down a jaunter wormhole with 10 tracking beacons on you, shouted "scramble!" and spam clicked a morgue tray, thus randomizing the entire 6x6 area around yourself?
Have you tracking implanted a clown, given him a camera bug, and morgue trayed him away from any and all danger, ruining everyone else's day?
Consider what we stand to lose here! Don't take my baby away!
