Implement modern file manager with drag-and-drop interface
Major UI/UX improvements to replace clunky sidebar with modern grid layout: - Add FileManagerModern component with grid-based file browser - Implement drag-and-drop file upload with validation and progress - Add comprehensive context menu with file operations (copy/cut/paste/delete) - Create intelligent file selection system with multi-select support - Add modern toolbar with search, view switching, and file operations - Integrate seamless view switching between classic and modern interfaces - Support keyboard shortcuts and accessibility features - Add complete i18n support for all new interface elements Technical components: - FileManagerGrid: Grid layout with breadcrumb navigation - FileManagerContextMenu: Right-click context menu system - useFileSelection: Hook for managing file selection state - useDragAndDrop: Hook for handling drag-and-drop operations - View switching logic integrated into main FileManager component The modern interface is now the default while maintaining backward compatibility. Users can switch between modern and classic views seamlessly.
