/**
 * @description A component that provides language selection functionality for applications.
 *
 * This component displays available languages and allows users to select their preferred language.
 * It adapts its display based on the number of available languages:
 * - For 1 language: No selector is shown
 * - For 2-3 languages: Displays a dropdown menu
 * - For 4+ languages: Opens a modal dialog with the full list
 *
 * The component integrates with EuiAppShellService to manage language state
 * and uses TranslateService for localization.
 *
 * @usageNotes
 * ### Basic Usage
 * ```html
 * <eui-language-selector></eui-language-selector>
 * ```
 *
 * ### In Toolbar
 * ```html
 * <eui-toolbar>
 *   <eui-language-selector [isToolbarSelector]="true"></eui-language-selector>
 * </eui-toolbar>
 * ```
 *
 * ### Accessibility
 * - Provides default `aria-label` indicating current language
 * - Custom `aria-label` can be set via input
 * - Keyboard navigable dropdown and modal interfaces
 *
 * ### Notes
 * - Automatically detects toolbar parent and adjusts styling
 * - Language list is managed through EuiAppShellService
 * - Supports 2-3 languages via dropdown, 4+ via modal
