feat(ai-outfit): inline prompt preview + move settings to right (layout A)

- Drop the prompt-preview dialog; add a live inline preview pinned at the
  bottom of the left column: sample-row dropdown + read-only rendered text,
  refreshing on prompt edit / sample change, with a missing-{title} hint.
- Sample rows load from the chosen Excel (on browse, on startup from the
  remembered path, and from the run's loaded tasks).
- Move 生成设置 out of the left column into the right run column
  (_create_settings_group), so left = 数据源 + 话术 + 预览.
- Matches docs d79f881. Full suite green; offscreen window smoke passes.
