feat(marketing): add features step to wizard

This commit replaces the placeholder "Preferences" step in the marketing page's multi-step process with a new, functional "Features" step.

The `FeaturesStep` component is now imported and rendered as the third step, allowing users to add features. The step's title and description have been updated to reflect this change.
