fix: Add missing Korean and Japanese translations for updated English text

[NavyStack]

Korean translation is provided "as is".

• Rearranged the word order to better match Korean sentiment.
• Made adjustments to clarify subtle semantic differences in the original text, which may have identical translations in Korean.
• We have striven to maintain the original sentence structure as closely as possible.
• If the original text lacks a period, the translation into Korean also omits it, rendering the content as a short phrase rather than a full sentence.
