fix: WSPR infinite loop, earthquake/lightning icons now visible, add logging

CRITICAL FIXES:
1. WSPR Infinite Loop (FIXED!)
   - Removed pathLayers and markerLayers from cleanup useEffect deps
   - These state arrays caused infinite re-render loop
   - setPathLayers([]) would trigger another cleanup → infinite spam

2. Earthquake Markers Not Visible (FIXED!)
   - Added missing .earthquake-icon CSS class
   - z-index: 1000, pointer-events: auto, flexbox centering
   - Markers now render properly with 🌋 emoji

3. Lightning Markers Not Visible (FIXED!)
   - Added missing .lightning-icon CSS class
   - Same fix as earthquakes

4. Debug Logging Added:
   - Earthquakes: logs fetch count, marker creation count
   - Lightning: logs generation time, stats panel updates
   - Helps identify data vs rendering issues

Result: All three plugins now work correctly!
