OPT-23-28 review: the unheld-shortfall line says another battery or the grid

With A on Leftover solar and B on Cheap hours (the dynamic scenario, and the
owner's planned setup), the line said "The batteries cannot hold it all. The
grid covers N kWh", while B holds a full charge for the same hours. It now
says "The expensive hours need more than Leftover solar can hold. The rest,
N kWh, comes from another battery or the grid." (NL likewise). DOCS,
DECISIONS and the dayplan/homeview docstrings say the same. Text only.
