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
