Reduce ServerEnvironment propagation (#9642)
ServerEnvironment is a huge class with many accessors. In various places it's not needed

Remove it to reduce the ServerEnvironment view.

Idea here is to reduce size of some of our objects to transport lightweight managers and permit easier testing

Pathfinder is now tied to a generic map, not a ServerMap, it can be
ported to client
