feat(monopoly): add card deck visuals and rent/card animations

- Draw Chance and Community Chest card decks on the board center
- Add animated card draw with flip effect from deck position
- Add animated rent payment with money flying between players
- Integrate new Monopoly sound effects (purchase, expense, paid)
- Extract applyRent() to MonopolyLogic for cleaner state handling
- Update monopoly-cards spritesheet with new card art
