🚀 Fix Drift Protocol integration - Connection now working

✅ Key fixes:
- Bypass problematic SDK subscription that caused 410 Gone errors
- Use direct account verification without subscription
- Add fallback modes for better reliability
- Switch to Helius RPC endpoint for better rate limits
- Implement proper error handling and retry logic

🔧 Technical changes:
- Enhanced drift-trading.ts with no-subscription approach
- Added Drift API endpoints (/api/drift/login, /balance, /positions)
- Created DriftAccountStatus and DriftTradingPanel components
- Updated Dashboard.tsx to show Drift account status
- Added comprehensive test scripts for debugging

📊 Results:
- Connection Status: Connected ✅
- Account verification: Working ✅
- Balance retrieval: Working ✅ (21.94 total collateral)
- Private key authentication: Working ✅
- User account: 3dG7wayp7b9NBMo92D2qL2sy1curSC4TTmskFpaGDrtA

🌐 RPC improvements:
- Using Helius RPC for better reliability
- Added fallback RPC options in .env
- Eliminated rate limiting issues
