            ## Translation Update

            This PR updates the translation file with new strings extracted from the source code.

            ### Changes
            - Extracted new translatable strings using `lupdate`
            - Updated 30 language files in `src/translations/`
            - Languages: Italian, German, French, Spanish, Portuguese, Russian, Chinese, Japanese, Korean, Arabic, Hindi, and 19 more

            ### What to do next
            1. Review the new strings in `src/translations/qdomyos-zwift_*.ts`
            2. Contributors can now create PRs to add translations in their language
            3. Edit the `.ts` file for your language and add translations in `<translation>` tags
            4. Merge this PR to make new strings available

            ### Translation Files
            - Location: `src/translations/`
            - Format: `qdomyos-zwift_LOCALE.ts` (e.g., `qdomyos-zwift_it.ts` for Italian)
            - 30 languages supported

            **Note:** Strings marked as `<translation type="unfinished">` need translation.
