fix: Use dynamic analysis interval based on actual timeframe

- Replace hardcoded 300 seconds (5 min) with calculated interval from timeframe
- analysisInterval now correctly shows 3600 seconds (60 min) for 1h timeframe
- Timer will properly display correct intervals for all timeframes (5m = 300s, 1h = 3600s, etc.)
