feat(CUB-64): Docker runtime setup for development & deployment

- Backend Dockerfile: added curl install for health check (not in aspnet base image)
- Frontend Dockerfile: multi-stage Angular build with nginx serving
- Frontend nginx.conf: SPA routing, API proxy, SignalR WebSocket support, health endpoint
- Frontend .dockerignore: excludes node_modules, dist, .angular, etc.
- docker-compose.dev.yml: added PostgreSQL service, fixed frontend context path,
  renamed web service from control-center-web to extrudex-web, added DB env vars,
  proper service dependencies with health checks
- deploy.sh: updated service list to include PostgreSQL port
