Summary: Support wildcards in item names for the Top Hosts dashboard widget

Background: The Data Overview widget is deprecated and scheduled for removal in upcoming releases, with Top Hosts being the recommended replacement. While migrating our dashboards, we encountered a functional limitation that prevents a like-for-like transition.
