feat: switch ingress proxy to direct container IP routing and capture network metadata on launch

Browse Source 
Refactor proxy target resolution to connect straight to the container's bridge IP and container port, bypassing the host port-publishing layer entirely. Introduce `container_ip`/`container_gateway` fields captured from Docker inspect on each running instance, stored alongside status updates. Update the fake backend to emit realistic `NetworkSettings` with per-container IPs. Remove the now-unused `CONTAINER_PROXY_HOST` config default and the old `ports_json`-based host port lookup in the proxy router.
