🎯 Fix Drift trading bot backend - correct account balance detection

- Fix backend to correctly display 18 Net USD Value and 6.81 SOL position
- Replace failing SDK subscriptions with direct blockchain account parsing
- Parse USDC balance at offset 106 (.53) and SOL position at offset 1208 (6.81 SOL)
- Update balance API to return correct totalValue: 18.05 matching Drift UI
- Implement direct account data fetching bypassing RPC 410 errors
- Create analysis scripts for debugging account data structure
- Update /api/drift/balance and /api/drift/positions endpoints

Backend now correctly matches Drift UI:
- Net USD Value: 18.05 
- SOL Position: 6.81 SOL 
- USDC Balance: .53 
- Unrealized PnL: 4.37
