feat(marketing): Implement chart creation step

This commit introduces the second step in the marketing page's stepper, which allows users to create a chart. The previous placeholder content has been replaced with the new `ChartStep` component.

To support form functionality within this new step, the `Button` component has been updated to accept a `type` attribute (`button`, `submit`, `reset`), enabling proper form submission handling.
