feat(kimi-web): rework ask-user-question card as step-by-step wizard

[wbxl2000]

Related Issue

No related issue. This change addresses a UX problem in the web UI where the "Prev" / "Next" navigation for multi-question askUserQuestion prompts was hidden in the card header, making it easy to miss additional questions and accidentally submit before answering all of them.

Problem

In apps/kimi-web/src/components/chat/QuestionCard.vue, the previous/next buttons for multi-question prompts lived in the header and were easy to overlook. Users could select an answer for the first question and hit Submit without realizing more questions followed.

What changed

• Removed the small Prev/Next buttons from the header.
• Added a visible stepper (numbered dots) above the question text; answered steps are highlighted and dots are clickable for quick navigation.
• Reorganized the footer into a left-aligned wizard flow:
  • Primary action is "Next question" until the last step, then "Submit".
  • "Back" is shown for multi-question prompts.
  • "Dismiss" is de-emphasized as a plain-text button.
• Disabled "Next" until the current question is answered, and "Submit" until all questions are answered.
• Updated Enter key handling to advance to the next question when applicable.
• Updated en/question.ts and zh/question.ts locale keys.

A patch changeset has been added because the web app is bundled into the CLI release artifact.
