Text caret and “List is empty” text render black on dark panel (low contrast) in the Create Node window

Steps to reproduce:

1. Create a new 3D Unity project
2. Open Preferences → General and set Editor Theme to Light
3. Create any Shader Graph and open it
4. Open the Create Node window (right-click → Create Node or press Space)
5. Type a query that returns no results

Actual results: The text caret in the search field and the “List is empty” label render black while the Create Node panel background is dark, making them hard to see

Expected results: The caret/label should use a light colours for proper contrast and readability
