OPT-27 review: the kept forecast line says "kept for tonight"

With battery modes off the forecast is still read and shown (Settings,
Simple, and the Forecast tab), but no plan uses it, so "used for tonight's
plan" was not true there (UX-53). "Kept for tonight" is true in every
shape. NL "vanavond" read wrong after midnight; "vannacht" covers the
whole night. DECISIONS' "modes off: nothing reads the sensors" corrected.
