Fix trade detection: remove infinite pagination loop

- API returns latest 100 trades without pagination support
- Previous code was stuck in infinite while loop fetching same trades repeatedly
- This prevented initial trade fetch from completing and blocked polling
- Now fetches once per poll interval, allowing trades to appear in console
- Changed FILTER_BTC_15M_ONLY=false to show all market types
- Trades now properly detected and logged with full details
