fix(rectification): show spoken collect questions in the chat UI

Spoken collect prompts lived only in GET current_question. The chat never
parsed that field, Agent projections returned null after evidence writes,
and active_focus followups collapsed the questionId. Render the parsed
prompt, keep choiceReady on real cards, and give collect focuses a stable
domain-scoped id.
