fix(#1356): replace HTTPServer with ThreadingHTTPServer in multi-user bridge

The single-threaded HTTPServer queues requests sequentially, causing
60% timeout under 10 concurrent users (30s timeout, 7.8s avg).

Fix: use ThreadingHTTPServer (already defined in multi_user_bridge.py)
for thread-per-request concurrency.

- multi_user_bridge.py: line 2883 HTTPServer -> ThreadingHTTPServer
- world/multi_user_bridge.py: add ThreadingMixIn import + class, fix server init
