refactor(steps): simplify step presenters by removing unnecessary useImperativeHandle calls

- Removed useImperativeHandle and getValues from BenefitsStep, ChallengesStep, ChartStep, ContactsStep, FeaturesStep, FooterStep, and HeroStep components.
- Updated step presenters to directly use refs for improved data handling and validation.
- Enhanced code readability and maintainability by streamlining the presenter functions.
