Fix Soyas client to match other SWQOS clients

Previously Soyas returned early on successful send without:
- Any logging
- Polling for transaction confirmation

Now aligned with other SWQOS clients (zeroslot, lightspeed, etc.):
- Proper error handling with reconnect retry
- Always poll for transaction confirmation
- Log confirmation success/failure with elapsed time
