Improve model status indicators and tune timeouts

Green/red emoji circles replace Unicode symbols for at-a-glance model
readiness. Increase connect timeouts (10→30s) for cold model loading,
warm timeout (120→300s) for large models, and pull timeout (600→1800s)
to match route-level limit. Show error toast on SSE reconnection failure
instead of silently recovering.
