fix: use ThreadingHTTPServer to prevent blocking on concurrent connections

When using VS Code Remote or other tools that establish multiple HTTP
connections, the single-threaded HTTPServer can become blocked, making
the web dashboard inaccessible.

ThreadingHTTPServer handles each request in a separate thread, preventing
this blocking issue while maintaining the same API.
