[MIRROR] Adjusts Door Mapping Helper Layers [MDB IGNORE] (#14588)

* Adjusts Door Mapping Helper Layers (#68032)

Hey there,

Access helper layers are great and all, but they tended to have this sort of effect on maps where since they were on the same layer as all of the other mapping helpers for doors, they would just tend to cover up the smaller sprites the others used, like this:

So, this just switches up the layers a bit by having a new layer called `DOOR_ACCESS_HELPER_LAYER` (that is still above `OPEN_DOOR_LAYER`) just for Access Helpers, while every other airlock helper takes the `DOOR_HELPER_LAYER` (like before), which has been increased by 0.01 more funny number.

Ok?
