- Make all AI endpoints (health scores + investment recommendations)
fire-and-forget: POST returns immediately, frontend polls for results
- Extend AI API timeout from 2-5 min to 10 min for both services
- Add "last analysis failed — showing cached data" message to the
Investment Recommendations panel (matches health score widgets)
- Add status/error_message columns to ai_recommendations table
- Remove nginx AI timeout overrides (no longer needed)
- Users can now navigate away during AI processing without interruption

- Frontend container nginx listens on 3001 instead of 80 to avoid
conflicts with the host-level reverse proxy
- Removed certbot service, volumes, and SSL config from
docker-compose.prod.yml — SSL/certbot is managed at the host level
- Updated nginx/production.conf: HTTP-only (host handles TLS),
upstream frontend points to port 3001
- Updated nginx/ssl.conf frontend upstream to 3001 for consistency

Root cause of 502 errors under 30 concurrent users: the production server
was running dev-mode infrastructure (Vite dev server, NestJS --watch,
no DB connection pooling, single Node.js process).
Changes:
- backend/Dockerfile: multi-stage prod build (compiled JS, no devDeps)
- frontend/Dockerfile: multi-stage prod build (static assets served by nginx)
- frontend/nginx.conf: SPA routing config for frontend container
- docker-compose.prod.yml: production overlay with tuned Postgres, memory
limits, health checks, restart policies
- nginx/production.conf: keepalive upstreams, proxy buffering, rate limiting
- backend/src/main.ts: Node.js clustering (1 worker per CPU, up to 4),
conditional request logging, production CORS
- backend/src/app.module.ts: TypeORM connection pool (max 30, min 5)
- docs/DEPLOYMENT.md: new Production Deployment section
Deploy with: docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build
