Add /proxy/{sandbox_id}/{port}/* handler that reverse-proxies HTTP
requests to services running inside sandbox VMs. The sandbox's host IP
(10.11.0.{idx}) is used as the upstream target.
Includes port validation (1-65535) and shared HTTP transport for
connection pooling. Supports WebSocket upgrades for protocols like
Jupyter's streaming API.
This is an intermediate state — needs further work for the full code
interpreter feature.
