Add pause-aware goal reset timer with proper scene cleanup

- Add 3-second countdown timer after goal that resets the scene
- Timer pauses when game is paused, respecting pause state
- Freeze all game updates (puck, players, goals) during countdown
- Properly reset timer flags in create() to fix post-restart state
- Add safety checks in Player and Puck update to handle destroyed entities
- Remove player goal deceleration behavior (superseded by scene freeze)
- Add destroy() method to Player for proper resource cleanup
- Clean up goal event listeners before scene restart
