/**
 * EmptyState - A user-friendly placeholder component for displaying when no content or data is available.
 *
 * @description
 * The EmptyState component provides informative messaging and optional call-to-action elements when
 * lists, searches, or data sets return no results. It helps guide users with clear messaging and
 * actionable next steps to improve user experience during empty content scenarios. The component
 * features customizable icons, header and content text, and action buttons to direct users toward
 * productive alternatives. It's particularly useful for empty search results, first-time experiences,
 * cleared notifications, and any scenario where data absence needs clear communication.
