Statistics section: UI enhancements

[terlan98]

• Removed rectangular background from statistics circles
• Added progress description (like 7/10) under the percentage text
• Fixed decimal formatting issues
• Clamped percentage values to 0...100 range to prevent weird results, like 1000%

Tested it locally, looks good 👍
Short question regarding the behavior when dividing by 0:

1. Here, the progress shows NaN
   

2. Here, the progress is 100%
   

Is this the intended behavior?

Thanks for pointing out. I added a new commit that deals with such cases and ensures that we always show 0% instead of N/A 🙂

Tested locally, works as expected.
Code LGTM 👍
