fix(rendering): filter player hair geosets via CharHairGeosets.dbc

buildDefaultPlayerGeosets() was inserting all submeshIds 0-99 into
activeGeosets, showing every hair variation simultaneously. Now uses
the hairGeosetMap_ (from CharHairGeosets.dbc) to select only the
correct hair scalp geoset for the player's race/sex/style, matching
the existing NPC geoset filtering logic in EntitySpawner.
