Pull request overview

This PR adds real-time search functionality for boxes in the Hive CE Inspector DevTools extension. When users type in the search field, the box list is filtered to show only matching boxes, with an empty state displayed when no matches are found.

Changes:

• Added a search text field above the boxes list with real-time filtering
• Implemented case-insensitive search that filters box names
• Added empty state message when no boxes match the search query
• Updated padding to be consistent (8px) across search inputs
