feat: Helius primary + Alchemy fallback for trade execution

Browse Source 
- Helius HTTPS: Primary RPC for Drift SDK initialization and subscriptions
- Alchemy HTTPS (10K CU/s): Fallback RPC for transaction confirmations
- Added getFallbackConnection() method to DriftService
- openPosition() and closePosition() now use Alchemy for tx confirmations
- accountSubscribe errors are non-fatal warnings (SDK falls back gracefully)
- System fully operational: Drift initialized, Position Manager ready
- Trade execution will use high-throughput Alchemy for confirmations

# 1. Bot STARTS with fallback (Helius) - handles startup burst better (10 req/sec sustained)
# 2. After init, SWITCHES to primary (Alchemy) - more stable for trading operations
# 3. On 429 errors, falls back to Helius temporarily, then returns to Alchemy
