Backend now awaits the refresh in a thread executor instead of queuing a
background task, so the response returns only after data is written. Frontend
drops the 3s setTimeout and invalidates the cache immediately on success.

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.

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.
