What is the current behavior?

The header search component in both finefoods-antd and finefoods-material-ui examples was making unnecessary API calls when the search input was empty. This caused performance issues and unnecessary network requests every time the search value changed to an empty string.

What is the new behavior?

Added a guard condition to prevent API calls when the search input is empty or contains only whitespace. The search functionality now only triggers API calls when there's actual search content, improving performance and reducing unnecessary network traffic.

Changes made:

• Added if (value?.trim() === "") return; check in the useEffect hook for both examples
• This prevents refetchOrders() and refetchCouriers() calls when search input is empty

fixes #6982

Notes for reviewers

• The fix is minimal and consistent across both admin template examples (finefoods-antd and finefoods-material-ui)
• The change only affects the search behavior when input is empty - all other functionality remains unchanged
