Add Korean translations for Android and Linux

[ivLis-Studio]

Summary

This PR adds Korean (ko_KR) translations for both Android and Linux.

Changes

• Added Android Korean string resources in android/app/src/main/res/values-ko/strings.xml
• Added Linux Korean Qt translation file in linux/translations/librepods_ko_KR.ts
• Registered the Linux Korean translation in linux/CMakeLists.txt

Notes

• This only adds ko_KR for Linux and does not modify the existing translation set beyond that.
• Existing untranslated Linux locales already present in the repository were intentionally left unchanged.

Validation

• Matched Android string count with the base values/strings.xml
• Matched Linux message count with the existing translation files
• Did not run a full Android or Linux build yet
