OPT-17 review: title the forecast row on Home; test the hint and blank rows

The new status row's id `solar_forecast` had no Home title, so Home showed
it under the fallback "Inverter connection". Add "Solar forecast" /
"Zonneprognose" to ui_text, and checks for the title, the tomorrow-gap hint
and blank list rows (review mutations R7, R9, R14 now killed).
