Low-Resolution Icons in Search Window (Labels, Options, Tags, and Inspector Panel)

Steps to reproduce:

1. Create a new Unity project
2. In the Editor toolbar, click the Search button (located next to the Layers dropdown)
3. In the Search window, click the "Add new query block (Tab)" button
4. Observe the icon resolution for the Labels, Options, and Tags query blocks
5. Also inspect the icons and visuals in the Inspector panel within the Search window

Actual results: Icons for Labels, Options, Tags, and elements in the Inspector panel appear pixelated or low-resolution

Expected results: All icons should appear crisp and sharp, matching the standard resolution quality of the Editor UI
