fix: Add signal price parsing to n8n workflow

PROBLEM:
- Bot logs showing wrong prices ($30-43 vs actual $141-144)
- TradingView sending correct format: 'buy 1 @ 142.08'
- n8n Parse Signal Enhanced wasn't extracting @ price field

ROOT CAUSE:
- n8n workflow parsed ATR, ADX, RSI, VOL, POS, MAGAP, IND
- But @ price field was never extracted
- Bot fell back to undefined → used RSI value instead

SOLUTION:
- Added signalPrice extraction: /@\s*([\d.]+)/
- Returns signalPrice field in n8n output
- Bot receives correct price in body.signalPrice

IMPACT:
- Logs will show correct SOL price ($141-144)
- Database signalPrice field accurate
- BlockedSignalTracker can calculate correct P&L

FILES CHANGED:
- workflows/trading/parse_signal_enhanced.json

NEXT STEP:
User must import updated workflow into n8n
Then 1-minute signals will log correct prices
