/**
 * Base component for selection lists that provides common UI structure
 * and keyboard navigation logic via the useSelectionList hook.
 *
 * This component handles:
 * - Radio button indicators
 * - Item numbering
 * - Scrolling for long lists
 * - Color theming based on selection/disabled state
 * - Keyboard navigation and numeric selection
 *
 * Specific components should use this as a base and provide
 * their own renderItem implementation for custom content.
