Greptile Overview

Greptile Summary

Fixed the System field in the resource details drawer to only display when a system_key value exists, replacing the previous behavior that would show the row with a boolean false value as children when no system was assigned.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a straightforward UI improvement that uses proper conditional rendering to hide empty fields. The implementation uses the spread operator correctly to conditionally include the system row only when system_key exists and is truthy, which prevents displaying incorrect boolean values in the UI.
• No files require special attention
