Use number format setting for attribute rows

Breaking change

Proposed change

Rendered attributes in an Entities card did not adhere to the new number format setting.

The red values all share the same source, but the first one is an attribute row and the other two are a template sensor based on that attribute (frontend correctly handled those states already).
