Fix invisible walls from WMO doodad M2 collision and MOPY filtering

Browse source 
WMO interior doodads (gears, decorations) were blocking player movement
via M2 collision. Skip collision for all WMO doodad M2 instances since
the WMO itself handles wall collision.

Also filter WMO wall collision using MOPY per-triangle flags: only
rendered+collidable triangles block the player, skipping invisible
collision hulls.

Revert tram portal extended range (no longer needed with collision fix).
