Fix database race condition and Drift initialization errors

- Remove saveTradeState() call from addTrade() to avoid P2025 error
- Add initialization check in checkTradeConditions() to skip when Drift not ready
- Silence 'not initialized' errors during startup (expected behavior)
- Trade state is now saved only by API endpoint after DB record created
