fix(complement-race): use sendMove with correct parameters for position updates

Fixed ReferenceError where makeMove was undefined. The correct function
is sendMove from useArcadeSession, which requires playerId and userId
parameters in addition to the move type and data.

Changes:
- Changed makeMove to sendMove
- Added playerId and userId to the move object
- Added localPlayerId guard to prevent updates before player is identified
- Updated dependency array to include localPlayerId, viewerId, and sendMove

This fixes the runtime error preventing ghost trains from working.
