feat: speech overflow fix, 60+ voice profiles, post-fight audio cleanup

- Change speak() default to cancelPrevious=true so voices don't queue endlessly
- Add stopAllAudio() export and wire into FightViewer unmount + post-fight
- Flush speech queue at fight end with delayed cancel for clean cutoff
- Expand from 30 to 60+ voice profiles (robots, accents, game, characters)
- Add speech bubbles showing bot responses during rounds
- Wire announceFinishHim/Fatality/FlawlessVictory/Devastating to not cancel
