fix: use Pyth price data for flip-flop context check

CRITICAL FIX: Previous implementation showed incorrect price movements
(100% instead of 0.2%) because currentPrice wasn't available in
check-risk endpoint.

Changes:
- app/api/trading/check-risk/route.ts: Fetch current price from Pyth
  price monitor before quality scoring
- lib/trading/signal-quality.ts: Added validation and detailed logging
  - Check if currentPrice available, apply penalty if missing
  - Log actual prices: $X → $Y = Z%
  - Include prices in penalty/allowance messages

Example outputs:
 Flip-flop in tight range: 4min ago, only 0.20% move ($143.86 → $143.58) (-25 pts)
 Direction change after 10.2% move ($170.00 → $153.00, 12min ago) - reversal allowed

This fixes the false positive that allowed a 0.2% flip-flop earlier today.
