Add improved costs card in the Energy dashboard

[MarByteBeep]

Currently there is no easy way to quickly get a historic daily overview of the costs in the energy dashboard. It would be great if that can be added. Also the current "Sources" card, that shows the costs, is quite clunky and not well positioned (somewhere in the middle of the page).

So it's not easy to quick;y glance at what the expenses were that day. A design like the current "Energy Distribution", but then for costs, would be preferred.
