fix: Increase transaction confirmation timeout to 60s for Alchemy Growth

- Alchemy Growth (10,000 CU/s) can handle longer confirmation waits
- Increased timeout from 30s to 60s in both openPosition() and closePosition()
- Added debug logging to execute endpoint to trace hang points
- Configured dual RPC: Alchemy primary (transactions), Helius fallback (subscriptions)
- Previous 30s timeout was causing premature failures during Solana congestion
- This should resolve 'Transaction was not confirmed in 30.00 seconds' errors
