To Reproduce
Steps to reproduce the behavior:

1. Go to 'CWA Stats'
2. Click on 'Library Stats'
3. Scroll down to any of Added Books, Total Formats, Library Growth Over Time, Largest Series, Publication Year Distribution, Rating Statistics, Format Distribution
4. See error: All display "No data available" Cross checking in System Stats shows that books have been added, converted, etc.

Correct data should be presented in appropriate sections.

I migrated the library database file to an NVMe drive Discord Post and now the Library Stats page appears to be populating correctly.

Not sure why this may have fixed it - reduced database latency, perhaps?
