ActionButton class
A compact, styled button designed for use in dialog footers and inline prompt panels.
Unlike Button, which is a full-featured button with multiple variants and sizes, ActionButton is intentionally simple: a text label wrapped in a colored container that responds to hover, selection, and tap.
Uses DialogThemeData for colors when available, falling back to semantic theme colors.
ActionButton(
label: 'Allow once',
isSelected: _selectedIndex == 0,
onTap: () => _handleAllow(),
