Message Router — FastAPI application.

The router is an internal service. In the current architecture (Phase 1),
routing logic is embedded directly in the channel gateway handlers rather
than as a separate HTTP call. This FastAPI app provides a health endpoint
and is a placeholder for future standalone router deployments.
