Backend adds valid_from to DateRateInfo and computes date_last_updated dict
(max valid_from across categories per date). Frontend renders it as a small
timestamp below the date in each column header — time only if today, date+time
if older. Full ISO string in title tooltip.

These two endpoints were missed in the central settings migration. They now try
the Settings service first and fall back to app-local system_config.

Stack-wide NewBook config lives in the Settings app (LXC 116) and is
fetched live via SETTINGS_URL/SETTINGS_SECRET — same pattern as cashup,
room-planner and maintenance. App-local system_config credentials remain
as a fallback for standalone/dev use. The app's Settings → Newbook page
no longer edits credentials; it points to the central app and keeps
Test Connection.

Python FastAPI ML backend kept intact; auth replaced with central hnf_session cookie verification. Frontend rebuilt on React 18 + TS + Vite with stack design system, Plotly charts retained. Shared Postgres via DATABASE_URL; schema applied on startup.
