fix: both-wrong draws + double TTS entrance fix

Scoring: both-wrong is now a DRAW — equal scores (3/3), no winner,
symmetric minimal damage. Garbage answers no longer beat reasonable
ones just by being faster. Both-wrong narrations reflect the draw.

Entrance: removed duplicate announceDeepIntro() call from FightViewer
(was already called inside playEntrance). Removed _resetPositions()
after entrance (entrance already places fighters at home positions,
the extra reset caused a visible snap/reset).
