The card is fed the model's raw tool input, so a malformed line (a
null, or a qty that is not a number) reached the renderer unchecked
and null.sku threw during render — taking the card, and its
Approve/Reject buttons, with it.
Lines are now read the way the MCP route reads them: an unreadable
line is reported in place, the good lines beside it still render, and
the operator is told that approving rejects the whole batch.
The headings stay put as well. The table now rides inside the card's
own scroller instead of a second scroll region, the header row is
sticky on an opaque background, and the set/add note rides with it —
so every row of a 40-line stocktake is read with its labels and its
mode in view.
