fix: Add close price to 1-minute data feed webhook

PROBLEM:
- Logs showing wrong prices: $30-43 when SOL actually at $141-144
- Webhook message missing close price field
- Bot falling back to RSI/ATR values (30-40 range)

ROOT CAUSE:
- TradingView indicator sending: 'SOLUSDT buy 1 | ATR:X | ADX:Y...'
- No @ price field in message
- n8n couldn't extract signalPrice, bot used wrong fallback

SOLUTION:
- Added close price to webhook format
- New format: 'SOLUSDT buy 1 @ 143.50 | ATR:X | ADX:Y...'
- Matches main trading signal format (v9 uses same pattern)

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

FILES CHANGED:
- workflows/trading/moneyline_1min_data_feed.pinescript

User deployed updated indicator to TradingView ✅
Next 1-minute alert will show correct price
