UI not built

The API is running, but no frontend bundle has been built into nodum/_web/. Build it once, then reload this page:

1. make web-install — install the Node dependencies
2. make web-build — build the bundle into nodum/_web/

For frontend development, make web-dev runs the Vite dev server on http://127.0.0.1:5700 and proxies the API back to this process.

The REST API is unaffected and available at /api; liveness is at /healthz.
