/// Dialog component with proper accessibility and styling variants
///
/// The Dialog component provides accessible modal dialog functionality with
/// proper ARIA attributes, keyboard navigation, focus management, and flexible styling.
///
/// # Features
/// - Proper modal semantics and accessibility
/// - Focus management and keyboard navigation
/// - Escape key handling
/// - Backdrop click handling
/// - Multiple variants and sizes
/// - State management (open/closed)
/// - Event handling
///
/// # Example
///
/// ```rust,no_run
