[MIRROR] Tweaks some instances of get_safe_turf so things like the nuclear disk doesn't accidentally teleport to the Icebox Syndicate Base (#28184)

* Tweaks some instances of get_safe_turf so things like the nuclear disk doesn't accidentally teleport to the Icebox Syndicate Base (#83012)

Yes, I know preventing the nuke disk teleporting to the icebox syndicate
base (or possibly the wendigo arena) is removing soul. Please don't kill
me :(

## About The Pull Request

Adds some missing variables to instances of get_safe_turf() so they will
only teleport to the given z-level.
Replaces some instances of get_safe_turf() with
get_safe_random_station_turf().

## Why It's Good For The Game

First, the differences between get_safe_turf() and
get_safe_random_station_turf():

### get_safe_turf()
- gets a random safe turf on a z-level (usually any of the staiton
z-levels), not accounting for the /area/
- should be used if you don't care if it spawns on the station or not,
or if you need to specifically teleport to a z-level
- not very expensive performance wise

###  get_safe_random_station_turf()
- gets a random safe turf that will always be a station area, ignoring
z-level.
- should be used if you NEED the turf to be on a station's area
- slightly more expensive performance wise than get_safe_turf, but still
very cheap

Some code was using get_safe_turf() when it should've been using
get_safe_random_station_turf(), and some code that should be using
get_safe_turf() were incorrectly using the zlevels arg instead of zlevel
arg (Yes, there is a difference), or didn't include it at all.

All the changes were made to my best judgement. If you're curious about
a change, please ask and I will explain why I did it.
