[codex] Add missing model Electron download UI regression test

[benceruleanlu]

Summary

• add a post-install Electron regression test for missing-model direct downloads
• reproduce the desktop path where the button should switch from Download to active/imported UI states
• assert the downloaded file lands in the expected models directory

Why

Prod downloads were succeeding in Electron, but the Missing Models row stayed in the default Download UI state. This PR captures that regression at the desktop app level before the frontend fix is consumed.

Impact

This PR is intended to be the red test in the stack. The current released desktop frontend does not reflect direct Electron download progress in this UI path, so this spec should fail until the frontend fix lands.

Validation

• yarn prettier --write tests/integration/post-install/missingModelDownloadUi.spec.ts
• yarn eslint tests/integration/post-install/missingModelDownloadUi.spec.ts --fix
• attempted: COMFYUI_ENABLE_VOLATILE_TESTS=1 yarn playwright test tests/integration/post-install/missingModelDownloadUi.spec.ts --project post-install

Notes

The Playwright run did not complete cleanly in the local environment because the existing post-install setup timed out and teardown hit EPERM: operation not permitted, scandir '/Users/ben/Documents/ComfyUI'. That blocked a clean local red/green confirmation, but the spec itself is in place for CI.
