fix(nav): remove play arrow badge from turn indicators

Removed the ▶ arrow badge from both local and network player turn indicators.
Turn indication is now shown through:
- Border ring with player color (pulsing)
- "Your turn" / "Their turn" text label below avatar
- Size increase and animation (local players only)
- Opacity dimming of non-current players

The arrow badge was unnecessary visual clutter with the text labels providing
clear indication of whose turn it is.
