feat: animate AI chip placement in Craps

Adds a staggered slide-and-fade animation for AI bets in Craps, making chips appear to fly from each player's seat to the felt. Updates `renderAiBets` to accept an `animate` flag and triggers the effect only during the betting phase. Removes the call from `beginRound` to avoid redundant rendering.
