fix(physics): keep remote placement and targeting in one world frame

Browse source 
CreateObject positions are landblock-local, but Runtime first-entry previously submitted remotes with a zero world offset. Runtime now owns the accepted local-player world-frame center and converts remote placements before SetPosition. The local physics host also publishes body.Position rather than CellPosition's landblock-local origin, so TargetManager no longer directs monsters toward a phantom player position. User gate: monster/static placement, chase, and attacks accepted outside Tusker Barracks.
