Add instant particle refresh on map interactions

- Clear and reload particles immediately on pan end (moveend event)
- Clear and reload particles immediately on zoom (zoomend event)
- Clear and reload particles on drag end (dragend event)
- 50ms delay for pan/zoom, 30ms for drag for optimal responsiveness
- Comprehensive console logging for each interaction type
- Update UI to highlight interactive particle refresh features

User experience:
- Pan the map → particles clear and reload instantly
- Zoom in/out → particles refresh immediately
- Drag and release → instant particle update

Matches professional weather visualization behavior
