[Bug]: foating-point precision in Insights metrics

[RaviRu11d]

Bug Description

In insights -> Overview [Mood over time], [Average urge intensity] have long decimal values e.g: 4.333333333333333.

Steps to Reproduce

*wipe all data

• created three tracks with distress [5], [7], [5]
• check the insights
• check the graph values in both [Mood over time], [Average urge intensity]

Expected Behavior

Round mood and average urge values to 1 decimal place at the service layer

instead of 4.333333333 it should have been 4.3 instead.

I have made a PR for a fix, if you can check it. Also it is my first PR :) Please check!
