Manual backport of #10856 to `core/1.43`.
## Conflicts resolved
Two files had trivial conflicts from the same root cause — #10856
extracted the inline `cleanup_fake_model` block into a shared
`cleanupFakeModel` helper in
`browser_tests/tests/propertiesPanel/ErrorsTabHelper.ts`:
- `browser_tests/tests/errorOverlay.spec.ts`
- `browser_tests/tests/propertiesPanel/errorsTabMissingModels.spec.ts`
`core/1.43` still carries the original inline
`expect(cleanupOk).toBeTruthy()` form. main's version (post-#10967) uses
an inline `expect.poll()` instead. #10856 replaces both with `await
cleanupFakeModel(comfyPage)` calling the helper added by this same PR.
Resolution: accepted the PR version (helper call) on both conflict
sites. The helper itself is added as part of this backport, so no
runtime behavior is lost.
## Verification
- No residual conflict markers
- Cherry-picked commit carries the entire #10856 squash (45 files,
+3596/-209)
## Original PR summary
See #10856 for full behavioral description, test plan, and screenshots.
