fix(tests): remediate known issues in LoginModal and VideoCard tests

- Fix `LoginModalController` async activity leak by binding `setTimeout` to `this.window`.
- Fix `VideoCard` moderation test by explicitly updating `ModerationDecorator` settings.
- Verify `popover.spec.ts` issue persists and update `KNOWN_ISSUES.md`.
- Update `KNOWN_ISSUES.md` to reflect fixes and current status.
