Malte Langkabel eb1572cd80 Show total building block cost in multi-selection panel
Implement the REQ-UI-MULTI-SELECTION addition: the selected building
panel now shows the total placement cost of a multi-selection, counting
only player-placeable buildings (HQ and defence stations excluded).
Construction sites are charged their type's full cost.

Add a shared BuildingsConfig::findBuildingDef accessor and reuse it in
BlueprintPanel to remove the duplicated by-type lookup loops.
