fix(collab-web): render the user-added note in ask tool cards

The ask tool stores the user-attached note in result details (note on the
single-question shape, per-item note inside results[]), but the shared
tool renderer dropped it: AskAnswer carried no note field and the card
never rendered one. Extract and render it as a muted row so HTML exports
and the collab guest view keep the user's context.
