[MDB IGNORE] Makes only station areas, station areas. (#70182)

* Makes only station areas part of Statioj

* Makes only subtypes of /area/station be part of the station
* Removes Icemoon and Shuttles as a check for Anomaly placers as they aren't needed anymore, not being part of shuttles.
* Removes a ton of uses of NO_ALERTS where it is no longer needed.
