feat(VocabPracticeDialog, localization): implement last wrong answer review feature

- Added a new section in VocabPracticeDialog to display the last incorrect answer, including the asked vocabulary, user answer, and correct solutions.
- Updated localization strings in Cebuano, German, English, Spanish, and French to support the new review feature, enhancing user experience across multiple languages.
- Improved UI layout for the review section to provide clearer feedback during vocabulary training sessions.
