feat: add comprehensive CI/CD pipeline with auto-promotion and testing

🚀 Enhanced GitHub Actions workflows:
- Add Playwright testing to all deployment pipelines
- Implement auto-promotion from develop → staging → master
- Add visual regression testing with screenshot artifacts
- Create PR validation workflow with local testing
- Add performance testing and health checks
- Implement timestamped artifact uploads
- Add comprehensive test result reporting
- Include Kubernetes manifest validation

🧪 Testing improvements:
- Multi-browser testing (Chrome, Firefox, Safari)
- Mobile device testing (Pixel 5, iPhone 12)
- Environment-specific test validation
- Security header validation
- Health endpoint testing
- Performance benchmarking

🔄 Auto-promotion flow:
- develop → staging (automatic PR creation after tests pass)
- staging → master (automatic PR creation after tests pass)
- Manual review required for production deployment
- Full test validation at each stage
