クローラのアカウントがリジャッジ権限を持つコンテスト(例: CodeQUEEN
予選と合同開催された abc308/abc358/abc410)では、提出一覧の各行の先頭に
リジャッジ用チェックボックス列が1つ追加され、以降の列が右に1つずれる。

parse_submissions_html は td:first-child / td:nth-child(N) と位置依存で
列を取得していたため、ずれた行で <time> 等が見つからず全行スキップし、
提出0件としてパースしていた。結果、これらのコンテストの提出が一切
取り込まれず、AC が AtCoder Problems に反映されなかった。

先頭のチェックボックス列の有無でオフセットを判定して吸収し、提出詳細
リンクはクラス(a.submission-details-link)で特定する方式に変更。通常
コンテスト(チェックボックス列なし)の挙動は不変。

実際に abc308 の提出一覧(管理者ビュー)を取得したスナップショットを
回帰テスト用フィクスチャとして追加。
