Main placeholder to show aggregated value instead of current state

[aaaaahaaaaa]

Perhaps subjective, but I find very confusing from a UX POV (and also kinda useless), that the card's main label still shows the current state value when grouping and using an aggregating function, instead of a value relevant to the aggregation. E.g.: when grouping power consumption by date over 7 days, the main label should allow to display the overall consumption over the total period.

In terms of configuration/UX, I think there's a simple and elegant way to achieve that: the aggregate_func config at the entity level should be the only the config for the entity, not an override, defining how the value is calculated for each group. And the aggregate_func config at the root level should define how the value is computed for the entire graph (main label).
