fix: eliminate excessive P&L calculations and restore CoinGecko price source

- Fixed Prisma table name errors in price-monitor.ts (trades vs trade, automation_sessions vs automationSession)
- Commented out excessive P&L calculation logging in analysis-details API that was processing all 69 trades
- Restored CoinGecko as primary price source (was falling back to Binance due to DB errors)
- Optimized analysis-details to skip P&L calculations for FAILED/EXECUTED trades
- Added comprehensive cleanup system for orphaned orders
- Performance improvement: eliminated unnecessary processing of old trade data

Result: Clean logs, efficient price fetching from CoinGecko, no excessive calculations
