refactor(desktop): share the clarify choice row and fix skip copy

Builds on the skipped-clarify card so it holds up beyond the timeout case:

- Extract a shared `ChoiceButton` (letter badge + label + row chrome) used
  by both the live pending card and the settled skip card. The two blocks
  had drifted into duplicated markup; now they can't diverge.
- Fix the hint copy. An empty `user_response` is emitted for BOTH a
  server-side timeout AND a manual Skip (tools/clarify_tool.py) — there is
  no field on the result that tells them apart — so asserting "This question
  timed out" was wrong half the time. Neutral wording ("This prompt is no
  longer waiting…") is correct for either, and the recover-your-answer path
  now also helps someone who mis-clicked Skip. Updated en/ja/zh/zh-hant.

No behavior change to the live prompt or the follow-up-message flow.
