feat: add debate arena and fix multiple issues

- Add AI debate arena for multi-AI trading decisions - Fix debate consensus calculation and display - Fix vote parsing to support both <decision> and <final_vote> tags - Fix JSON field name compatibility (stop_loss/stop_loss_pct) - Fix symbol validation to prevent AI hallucinating invalid symbols - Fix Bybit position side display (was uppercase, now lowercase for consistency) - Fix NOFX logo navigation to home page - Add detailed logging for debugging trade execution
