/**
 * File Upload - A comprehensive file upload control with drag-and-drop support and multiple view modes.
 *
 * @description
 * The File Upload component provides a complete file upload workflow with drag-and-drop functionality,
 * multiple view modes (list, table, card), upload progress tracking, and extensive customization options.
 * It supports single and multiple file selection, file type restrictions, size validation, custom upload
 * strategies, and comprehensive file management features. The component handles file selection via dialog
 * or drag-and-drop, displays upload progress, provides error handling and retry mechanisms, and offers
 * different visual representations for uploaded files. Features include file preview capabilities,
 * batch operations, upload resumption, and integration with various backend services. Perfect for
 * document management systems, media upload interfaces, form attachments, and any application requiring
 * robust file handling capabilities.
