test(web): cover collapsing and expanding the question card

Two new QuestionComposer cases: the collapse toggle hides the option list
and leaves the header strip, and collapsing between answering preserves
both the picked draft and the current question position through a full
submit; re-expanding does not steal focus back into the textarea. Refresh
the question-composer and steering web e2e goldens for the new header
button.
