fix(ai): show answered ask_questions as a card in chat history (#23075)

## Context

Feedback on the `ask_questions` (Ask AI) tool:
- When answering a select prompt with a free-form message, the answer
wasn't surfaced as expected in the conversation history.
- The selected value also looked dropped once picked.

Root cause: answered `ask_questions` parts were caught by the
thinking-steps grouping and rendered as a generic collapsible "Ran
ask_questions" tool step (JSON output), so the dedicated renderer was
never reached.

## Changes

- **Render answered questions as a card**
(`AiChatQuestionStatusRenderer`): an "Answers" card that shows each full
question with the chosen option label(s) or the free-text answer beneath
it, instead of the faint inline `header: value` line.
- **Free-text keyboard navigation** (`AiChatQuestionCard`): pressing
Enter in the free-text area now advances to the next question, or
submits when on the last question (mirroring the option-select flow).
Shift+Enter still inserts a newline.

## Notes

- No schema/GraphQL changes; display + interaction only.
- Existing `thinkingStepsDisplayState` grouping test is unaffected (only
`web_search`/`create_task`/`code_interpreter` are used there).
