feat(web): answerable ask_user_question flow with toolview verdict row

The pending question now owns exactly two surfaces: the redesigned
QuestionComposer takeover (footer pager, checkbox multi-select,
always-visible custom input, locale-injected bilingual chrome) collects
the answers, and a dedicated ask_user_question toolview row reports the
interaction outcome — waiting, N/M answered, cancelled (ASK_CANCELLED),
or interrupted with stopped semantics (ASK_ABORTED). PendingCard narrows
to approval waits only. Toolview leading icons and the hover chevron
unify on the tertiary label color, the checklist glyph matches the
14px figma extract, and dev-watch registers CSS modules so css-only
edits rebuild.
