Revamp the document list experience by introducing a Finder-style window
interface with multiple views (icons, list, columns, gallery) and a new
sidebar filter system. Remove legacy folder and list item components in
favor of modular, windowed views. Integrate react-dnd-touch-backend and
custom DnD context for improved drag-and-drop, including mobile support.
Update uploader and dialog styles for consistency. Extend document types
to support new view modes, icon sizing, and sidebar state.
Update modal components to start from top on mobile devices and center on larger screens, improving usability across screen sizes. Also refine transition handling in privacy popup for cleaner unmounting.
