[Improvement]: i18n for logs

[nosovk]

Improvement description

Errors that thrown during import are shown in import log.
It's great, but those errors have no transliteration. They are always in English, and there is no way to translate them for end user, because error description hardcoded into bundle.

the challenge will be how to pick the language the logs should be translated into. good ideas are welcome.

[nosovk]

for example based on language used by viewer?
Unfortunately we will need to parse logs before showing them, it could be bad for big amount of data inside logs.
