Keep dev dependencies in the container so it can compile at start

NODE_ENV=production makes 'npm ci' omit devDependencies, which stripped
typescript and tsx from the bind-mounted node_modules on first start and left
the entrypoint unable to build. Both RELAY_MODE=prod (tsc) and dev (tsx watch)
compile from source at runtime, so the dev dependencies have to stay.
