feat(i18n): polish JA/ZH/KO translations for natural phrasing

Replace stilted machine-style phrasings across Japanese, Chinese, and
Korean with idiomatic equivalents native speakers would actually use.
Examples: "ダッシュボードへ戻る" -> "ホームに戻る", "返回仪表盘" ->
"返回主界面", "검사 패널" -> "상세 정보", trim labels normalized to
en-dash minus signs, and various awkward terms simplified.
