Added a solar activity chart to the app

I've integrated solar activity tracking into the app — daily data on solar flares, the Kp index, and magnetic field variations.
The chart updates in real time with data from NOAA.

All data is stored in a local database, with 4 years of historical records already in place.
This lays the groundwork for potential analysis of correlations between solar activity and user behavior or well-being over time 🌞
