mindesbunister 7c4adff4e4 Implement risk checks: cooldown, hourly limit, and daily drawdown ...

Implemented 3 critical risk checks in /api/trading/check-risk:

1. Daily Drawdown Check
   - Blocks trades if today's P&L < maxDailyDrawdown
   - Prevents catastrophic daily losses
   - Currently: -0 limit (configurable via MAX_DAILY_DRAWDOWN)

2. Hourly Trade Limit
   - Blocks trades if tradesInLastHour >= maxTradesPerHour
   - Prevents overtrading / algorithm malfunction
   - Currently: 20 trades/hour (configurable via MAX_TRADES_PER_HOUR)

3. Cooldown Period
   - Blocks trades if timeSinceLastTrade < minTimeBetweenTrades
   - Enforces breathing room between trades
   - Uses minutes (not seconds) thanks to previous commit
   - Currently: 0 min = disabled (configurable via MIN_TIME_BETWEEN_TRADES)

Added database helper functions:
- getLastTradeTime() - Returns timestamp of most recent trade
- getTradesInLastHour() - Counts trades in last 60 minutes
- getTodayPnL() - Sums realized P&L since midnight

All checks include detailed logging with values and thresholds.
Risk check called by n8n workflow before every trade execution.
