Sleep and Idle Sessions Should Cut at Midnight

I seem to remember TeslaFi previously had cut the idle and sleep sessions at midnight when they start on one day and end on another. I think we even worked on putting that into place during initial QA of the site two years ago. 

In any case, is it possible to update the logic so that an idle or sleep session can effectively "cut off" at midnight (though I'm sure it can leep the same ID #) and the appropriate range loss in the right column is correctly respective of that day. Ideally, the Total Time for sleep and idle plus the Time Driven and Time Charging should always only add up to 24 hours, never more or never less, so we can show correct range loss for sleep and idle for that 24 hour period.
