UI polish: logo start screen, broadcast scoreboard, kill pips, best-run

- start screen: SPLATTER TENNIS logo + slogan, controls kept
- scoreboard redrawn as a real broadcast board (server ball, name, sets,
  games, highlighted points cell); weapon stock moved to a status strip
- kills-to-next-point pips (NEXT ○○○) so the K-kill gate is visible;
  TUNE.killPips toggles it
- miss-debug HUD off by default (TUNE.missHud 0), dev-only now
- eaten screen crows "NEW BEST" when the run beats the stored high score
