fix: update tests for template compression, pagination, and quality filtering

- Fix parameter validation tests to expect mode parameter in getTemplate calls
- Update database utils tests to use totalViews > 10 for quality filter
- Add comprehensive tests for template service functionality
- Fix integration tests for new pagination parameters

All CI tests now passing after template system enhancements
