Energy dashboard: show data for current hour in progress

At present, the Energy dashboard (and the cards on it) only shows data up to the end of the most recent hour. I’d like it to show whatever data it has up to the present instant, especially for things like the “Energy Distribution” card that give the impression they’re showing live data (rather than data that’s potentially 59 minutes out of date). This would also make the views for day/week/month/etc. more consistent with each other, since for example the week view will already show data for the day in progress (up to the most recent hour).

I think that it would be nice to mark the current time period in bar graphs somehow to indicate incomplete data, but I also don’t think this would be needed for a first pass.
