SCCV Horizon Aft Extension & Partial Remap (#21495)

**Overview:**
The first huge fuckoff mapping PR for giving the Horizon enough extra
space to be able to comfortably map on it for the duration before NBT2
and not be super cramped (extends aft by 6 turfs).

Includes a SECOND vault to heist at the back of the ship and a lot of
maint area people can repurpose. Notably, this also removes the Xenobio
Hazardous Containment room and the Medical Emergency Storage room
(contents of the latter have been moved). Otherwise, y'all got more
ship.
