Complete Korean translation based on English file

[jelveh]

The Korean translation file (ko.js) needs to be updated to include all translations present in the English file (en.js). Currently, the Korean translation may be incomplete or outdated compared to the English version.

Steps to resolve

1. Compare the contents of src/gui/src/i18n/translations/en.js and src/gui/src/i18n/translations/ko.js
2. For each translation key in en.js, ensure a corresponding translation exists in ko.js
3. If a translation is missing in ko.js, add it with an appropriate Korean translation
4. If any translations in ko.js are outdated or incorrect, update them to match the current English version

Additional notes

• Please ensure that the translations are culturally appropriate and maintain the intended meaning of the English text
• If certain terms or phrases don't have a direct Korean equivalent, consider adding translator notes or using transliteration where appropriate

Files to be updated

• src/gui/src/i18n/translations/ko.js
