Show previous scrambles for completed solves

Users should be able to view scrambles associated with completed solves.

Feedback source:
- Viewing previous solves' scrambles.
- Add ability to see previous scrambles.
- Put scrambles to be seen after having done the solve.
- Not allowing a solver to access a scramble they have previously done in the timing area, while still being able to access it in chat/history.

Acceptance ideas:
- Store/display the scramble for each completed attempt.
- Make previous scrambles accessible from result history or solve details.
- Keep completed scramble review separate from the active timing area.
- Define behavior when a room expires or is deleted.

まず、完了した試行がどのように保存され、結果履歴またはsolveの詳細がどのように表示されるかを追跡します。エントリーポイントを選ぶ前に、アクティブな計測領域と、ルームの期限切れまたは削除の挙動を確認します。完了とは、アクティブな計測フローを通じて利用可能にすることなく、完了した各solveのscrambleが履歴で確認できる状態です。
