Implement /v2 prototype UI with page-based navigation

- Add /v2 route structure with dynamic nested directory pages
- Create V2DirectoryView component with breadcrumb navigation
- Add V2MoveDialog with directory search and flat list display
- Implement single upload button for current directory context
- Add /api/directories endpoint for move dialog directory picker
- Fix breadcrumb decoding to show readable names instead of URL encoding
- Add file sorting: directories first, then files, all alphabetically
- Improve performance by loading only current directory contents
- Add ScrollArea component and @radix-ui/react-scroll-area dependency
- Ensure proper URL encoding/decoding flow to prevent malformed paths
