fix: human fight UX — SSE challenge input, fighter sprites, battle log questions, left-side positioning

- Add SSE human_challenge listener for instant input activation with auto-focus
- Buffer challenges during 3s round cooldown, apply with correct remaining time
- Map 'human' archetype to fighter-looking archetypes (boxer, ninja, etc.) in sprite system
- Show challenge questions in battle log via round_start SSE events
- Ensure human players are always botA (left side) in queue matchmaking
