Add playing handicap, 6-digit login code, and game UX improvements

- Playing handicap: computed at game creation (WHS formula), stored on
  game_players alongside per-hole strokes allocation; displayed on game
  summary with HC card and / markers on scorecard (only when SI defined);
  live game shows +N per player card when SI exists, HC total otherwise;
  new game confirmation previews computed HC per player

- Login: 6-digit code sent alongside magic link in every auth email;
  check_email page has auto-advancing digit inputs with paste support;
  new POST /auth/verify-code route handles code verification

- Game view: Score/Card toggle fixed with position:fixed to always show
  above nav bar on mobile; swipe on score view changes holes, swipe on
  scorecard switches tabs; dirty tracking prevents saving unmodified holes
