Remove the 'production' stage from Dockerfile that was:
- Duplicating functionality already in Dockerfile.prod
- Incorrectly running 'bun run dev' instead of production command
VPS deployments continue to use Dockerfile.prod as the single
source of truth for production builds. Development Dockerfile
now only contains development stage.
- Remove web package.json install steps from Dockerfiles
- Remove web/dist copy from production build
- Remove web_node_modules volume from docker-compose
