Improve editor and cookie-consent test coverage, fix RegExp.exec lint

- Add 5 editor tests: toolbar mousedown, _sync, exec with/without value
- Mock document.execCommand for happy-dom compatibility
- Add cookie-consent test for duplicate script guard
- Use RegExp.exec() instead of String.match() per ESLint rule
