Subject: [PATCH] fix(local-llm): proxy extraction health check through API
 route

Move extraction service health check from direct browser fetch
(http://localhost:4005/health) to server-side /api/extraction/health
proxy. Eliminates ERR_CONNECTION_REFUSED console errors when the
extraction service is not running locally.
