Clean up old UI code and rename V2 to Drive

- Remove old UI components: file-drive.tsx, history-view.tsx
- Remove unused API endpoints: /api/tree, /api/log, /api/fs/route.ts
- Rename /v2 routes to /drive routes for cleaner URLs
- Rename V2* components to Drive* components (V2DirectoryView -> DriveDirectoryView, etc.)
- Update all breadcrumb and navigation references from /v2 to /drive
- Redirect root path to /drive instead of old UI
- Keep /api/fs/[...path] and /api/directories for uploads and move functionality
- Preserve Drive_* server functions for potential future use
