Option to display step headers vertically on the **left side** of the multi-step form

[kumard78]

Feature Request

I'd love to see an option to display step headers vertically on the left side of the
multi-step form, rather than the default horizontal layout at the top.

Why This Matters

• Improves UX for long forms by reducing vertical scroll
• Better suited for desktop layouts with wide screens
• Aligns with common UI patterns in enterprise apps and admin dashboards

Suggested Implementation

• Add a headerPosition="left" or similar prop to <FormKitMultiStep>
• Allow styling overrides for vertical layout (e.g., flex column, scrollable sidebar)

Bonus Points

If possible, support responsive behavior—vertical on desktop, horizontal on mobile.

Thanks for considering this enhancement!
