Make forfeit button always visible in player menu

Changed forfeit button to always be visible instead of only when player can lose:
- Removed conditional check in LifeCounter (always passes onForfeit)
- Removed conditional rendering in PlayerMenu (button always shows)
- Button remains functional with safety check inside onClick handler

This makes it easier for players to forfeit at any time during the game.
