fix(nav): remove animation/enlargement from network player turn indicator

When it's a network player's turn, the local player is waiting, not acting.
Network players now show turn indicators without animated/enlarged behavior:

- Border ring and arrow badge still show whose turn it is
- Avatar stays at normal size (56px, no enlargement)
- No floating/bobbing animation
- Opacity still changes to emphasize current player

This makes it clear which remote player has the turn while signaling that
no action is required from the current session.
