Simplify frontend by removing FileItem conversion layer

- Remove FileItem interface and 300+ lines of mock data
- Eliminate transformTreeNodes() conversion function
- Update component to use DriveTreeNode[] directly
- Rename /api/list to /api/tree with server-side tree building
- Add Drive_tree() function and DriveTreeNode types
- Significantly reduce code complexity and memory usage

-- Current page shows basic Next.js template but calls Drive_ls("/", false)

 ## API Endpoints
 
-### Legacy Endpoints
-- `/api/list` - GET all files recursively from root
+### Tree Endpoint
+- `/api/tree` - GET filesystem tree with hierarchy
 
 ### RESTful API - `/api/fs/[...path]`
 - **GET** `/api/fs/path/to/directory` - List directory contents
