tinkle-community fd8b1477e7 Fix: Resolve Trade History data loss and P&L calculation errors ...

Major fixes:
1. Trade History data loss issue
   - Root cause: Open records outside analysis window caused close matching failures
   - Solution: Pre-populate position state by reading 3x window of historical records
   - Ensures long-term positions (>5 hours) generate correct trade records
2. P&L calculation errors
   - Remove incorrect leverage multiplication from absolute P&L
   - Correct calculation: Futures P&L = quantity × price difference
   - Leverage only affects P&L percentage (relative to margin)
3. Other fixes
   - Break-even trades (pnl=0) no longer misclassified as losses
   - Perfect strategy shows Profit Factor as 999.0 instead of 0.0
   - Expand analysis window from 20 to 100 cycles (5 hours)
Files changed:
- logger/decision_logger.go: Core matching and calculation logic
- api/server.go: API analysis window
- trader/auto_trader.go: AI decision analysis window
