fix(frontend): 一部のページでもっと見るが自動で行われないバグの修正 (#16754)

* 一部のページでもっと見るが自動で行われないバグの修正

* fix(frontend): MkPagination で UI アニメーションオフ時に自動ロードが動作しない問題を修正

Transition コンポーネントの mode="out-in" が、アニメーション無効時でも
適用されており、IntersectionObserver の検出に干渉していた問題を修正。
アニメーション有効時のみ mode="out-in" を適用するように変更。

* enhance: ユーザーの設定値にかかわらず無限スクロールをオフにできるオプションを追加

* Update Changelog

* MkNotesTimeline.vueにforceDisableInfiniteScrollを追加、 note.vueの前方向の読み込みでこれを有効

* fix lint

* refactor
