Pull request overview

This PR targets the Greenhouse Admin Area DataGrid header/tooling UI to make the toolbar layout and styling consistent across the PluginPresets, Clusters, and Exposed Services tabs.

Changes:

• Moved the “Clear all” action next to the selected filter pills in PluginPresets.
• Applied consistent “light/gray” text styling for status/metadata lines in the toolbar area.
• Ensured the Clusters tab also wraps its toolbar content in DataGridToolbar for consistent structure/alignment.
