FormHeader class
A header component for forms in the Arcane UI system, providing a structured layout for labeling and displaying form elements.
This StatelessWidget creates a minimal vertical column that starts with a small-sized label text, followed by a small gap, and then the provided child widget.
It is designed for use in form sections to clearly delineate field groups or input areas, integrating seamlessly with ArcaneField, FieldWrapper, and other form-related components.
Key features include compact sizing for better space utilization in forms and support for any Widget as the child, allowing flexibility in form design.
Usage example: Wrap a TextField or Selector with FormHeader to provide contextual labeling within a Section or Carpet layout.
