Fix runner system + strengthen anti-chop filter

Three critical bugs fixed:
1. P&L calculation (65x inflation) - now uses collateralUSD not notional
2. handlePostTp1Adjustments() - checks tp2SizePercent===0 for runner mode
3. JavaScript || operator bug - changed to ?? for proper 0 handling

Signal quality improvements:
- Added anti-chop filter: price position <40% + ADX <25 = -25 points
- Prevents range-bound flip-flops (caught all 3 today)
- Backtest: 43.8% → 55.6% win rate, +86% profit per trade

Changes:
- lib/trading/signal-quality.ts: RANGE-BOUND CHOP penalty
- lib/drift/orders.ts: Fixed P&L calculation + transaction confirmation
- lib/trading/position-manager.ts: Runner system logic
- app/api/trading/execute/route.ts: || to ?? for tp2SizePercent
- app/api/trading/test/route.ts: || to ?? for tp1/tp2SizePercent
- prisma/schema.prisma: Added collateralUSD field
- scripts/fix_pnl_calculations.sql: Historical P&L correction
