Add debug logging for GameObject spawns to diagnose duplicate cathedral

Added detailed logging in spawnOnlineGameObject() to help identify duplicate
game object spawns. Logs displayId, guid, model path, and position for both
new spawns and position updates. This will help diagnose the floating
cathedral model issue in Stormwind by showing which GUIDs are being spawned
and their coordinates.
