Show an explicit error when no forecast is available

Browse source 
The Weather Compensation hint text only ever showed the forecast peak
when the fetch succeeded — a failure (bad location, wrong Met Office
subscription, etc.) just silently showed nothing, which is exactly what
happened debugging this live. Now shows a clear red hint pointing at the
two things most likely wrong (Integrations config, backend logs) once
the initial status fetch has resolved and come back empty.
