Pad praise score values in frontend

[Vyvy-vi]

Details

The total_praise_score values have long decimal values that terminate after a while but these are insignificant digits (perhaps it's time to look if there are some floating point inaccuracies in the codebase?)

Main success scenario

This shouldn't be displayed in the frontend. We should round or pad these these values to 2 or 3 decimal places to prevent weird UI breaks.

Who should be kept in the loop?
