[Copilot]

Pull Request Overview

This PR addresses three key issues: it fixes the form reset behavior (including for radio groups), adds an onChange event for user interactions, and updates demo/test snapshots accordingly.

• Updates RadioGroup props to support resetting with null values.
• Enhances the form API with new initial value and field value management functions.
• Adjusts snapshot tests and demo examples to incorporate the new “single-line” style and event handlers.
