Centralize player initialization to single addPlayer() method

Moved all player scene/physics setup from Player constructor to GameScene.addPlayer() to create a single source of truth for adding players. This prevents players from auto-rendering when instantiated and gives better control over when/how players are added to the scene.

Changes:
- Remove scene.add.existing() and physics setup from Player constructor
- Move physics body initialization to GameScene.addPlayer()
- Comment out second test player for single-player debugging
