Fix Drift balance calculation and implement multi-RPC failover system
- Fixed balance calculation: corrected precision factor for Drift scaledBalance (5.69 vs wrong 0,678.76) - Implemented multi-RPC failover system with 4 endpoints (Helius, Solana official, Alchemy, Ankr) - Updated automation page with balance sync, leverage-based position sizing, and removed daily trade limits - Added RPC status monitoring endpoint - Updated balance and positions APIs to use failover system - All Drift APIs now working correctly with accurate balance data
