fix(n8n): CRITICAL - Add quality score validation to old workflow path

PROBLEM:
- Trades with quality score 35 and 45 were executed (threshold: 60)
- Position opened without risk management after signal flips
- "Parse Signal" node didn't extract ATR/ADX/RSI/volumeRatio/pricePosition
- "Check Risk" node only sent symbol+direction, skipped quality validation
- "Execute Trade" node didn't forward metrics to backend

ROOT CAUSE:
n8n workflow had TWO paths:
1. NEW: Parse Signal Enhanced → Check Risk1 → Execute Trade1 (working)
2. OLD: Parse Signal → Check Risk → Execute Trade (broken)

Old path bypassed quality check because check-risk endpoint saw
hasContextMetrics=false and allowed trade without validation.

FIX:
1. Changed "Parse Signal" from 'set' to 'code' node with metric extraction
2. Updated "Check Risk" to send atr/adx/rsi/volumeRatio/pricePosition
3. Updated "Execute Trade" to forward all metrics to backend

IMPACT:
- All trades now validated against quality score threshold (60)
- Low-quality signals properly blocked before execution
- Prevents positions opening without proper risk management

Evidence from database showed 3 trades in 2 hours with scores <60:
- 10:00:31 SOL LONG - Score 35 (phantom detected)
- 09:55:30 SOL SHORT - Score 35 (executed)
- 09:35:14 SOL LONG - Score 45 (executed)

All three should have been blocked. Fix prevents future bypasses.
