[Desktop] Expand/collapse all button overflows with longer locale labels

Description

With the UI language set to pt-BR, the "Expandir tudo" (Expand all) button in the session review header overflows its border: the last character is rendered outside the button.

The button in packages/session-ui/src/components/session-review.tsx has a hardcoded width (class="w-[106px] justify-start"). "Expand all" fits in 106px, but longer translations do not, and since the label is not truncated it overflows over the border.

3. Look at the "Expandir tudo" button in the "Changes from last turn" header
