Codex desktop app: plugin search page blank overlay covers content

The Codex desktop app plugin/configuration page shows a large blank white overlay under the plugin search box, covering plugin list content.

Environment:

• App: Codex desktop app
• OS: macOS
• Page: Plugin/customization page ("让 Codex 按你的方式工作")

Steps:

1. Open the plugin or customization page.
2. Focus or use the plugin search box.
3. Observe the plugin list area.

Expected:
Plugin list and search results should be visible and clickable.

Actual:
A large blank white panel covers most of the content. The right-side card and some text are partially visible, but the layout is misaligned and hard to use.
