mindesbunister 6990f20d6f feat: Orderbook shadow logging system - Phase 1 complete ...

Implementation:
- Added 7 orderbook fields to Trade model (spreadBps, imbalanceRatio, depths, impact, walls)
- Oracle-based estimates with 2bps spread assumption
- ENV flag: ENABLE_ORDERBOOK_LOGGING (defaults true)
- Execute wrapper lines 1037-1053 guards orderbook logic

Database:
- Direct SQL ALTER TABLE (avoided migration drift issues)
- All columns nullable DOUBLE PRECISION
- Prisma schema synced via db pull + generate

Deployment:
- Container rebuilt and deployed successfully
- All 7 columns verified accessible
- System operational, ready for live trade validation

Files changed:
- config/trading.ts (enableOrderbookLogging flag, line 127)
- types/trading.ts (orderbook interfaces)
- lib/database/trades.ts (createTrade saves orderbook data)
- app/api/trading/execute/route.ts (ENV wrapper lines 1037-1053)
- prisma/schema.prisma (7 orderbook fields)
