Unified desktop app is missing a Codex Light icon option

Summary

After the recent unified ChatGPT/Codex desktop update, the app no longer appears to offer a true Codex Light icon option.

This is related to #28861, but it is not exactly the same issue. #28861 describes a case where a Codex Light option exists but renders like the Default icon. What I am seeing is that the unified app does not expose a true Codex Light icon/asset as a first-class choice.

Current behavior

• I can see/use a dark Codex icon.
• I cannot find a true Codex Light icon option in the app icon choices.
• The previous light Codex icon appears to be removed or inaccessible in the unified desktop app.

Expected behavior

• Restore Codex Light as a separate Dock/app icon option.
• The icon choices should include both Codex Light and Codex Dark.
• Codex and ChatGPT branding should each have clear light/dark icon options instead of only a partial mix, such as ChatGPT Light plus Codex Dark.
