Ensure that `wildcard` package doesn't rely on `web` package

Created by: valerybugakov

The wildcard package should not rely on the web and probably shared, branded too. Ideally, it should be an independent, self-contained package.

Right now, the Page Selector story relies on web-app styles and branded-story components. Page Header imports FeedbackBadge from the web package.

Consider not using web-app styles for wildcard stories.
