Add gradient backgrounds to all status messages, match final-turn badge size

- Default gradient on base .status-message (dark green)
- Add round-over/game-over (gold) and reveal (purple) gradient styles
- Tag action prompts (swap, flip, discard) as your-turn type
- Match final-turn badge font size and padding to status message on mobile
- Hide status message when empty
