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
