docs: add SonarCloud quality badges to all README files

Add comprehensive SonarCloud badges to README.md, README.ru.md, and README.tj.md:
- Quality Gate Status - overall project health indicator
- Coverage - code coverage metrics
- Bugs - bug count
- Code Smells - code quality issues
- Security Rating - security vulnerabilities
- Maintainability Rating - technical debt

All badges link to the SonarCloud project dashboard for detailed analysis.
