Move Hole indicator and End Game button to mobile bottom bar

- Add round info and leave button to mobile-bottom-bar HTML
- Hide .round-info and #leave-game-btn from header on mobile
- Style round info as subtle text, leave button as red-tinted pill
- Slim down bottom bar: smaller gaps/padding to fit 4 items
- Sync round numbers and leave text via JS (renderGame + bindEvents)
- Frees up header space, reduces mobile crowding
