Comprehensive health platform updates: synthetic data, operational tooling, and architecture reorganization

SYNTHETIC DATA GENERATION:
- Complete cancer_open_research_synthetic.sql with 300+ realistic cancer research records (2019-2022)
- Expand annual_death_cause_synthetic.sql with comprehensive death cause statistics
- Cover breast cancer, lung cancer, immunotherapy, AI/ML research, COVID-19 impact studies

OPERATIONAL TOOLING:
- Add health/flutter-frontend/deletepod.sh for healthai-frontend pod management with monitoring
- Add health/springboot-backend/deletepod.sh for healthai-backend-springboot pod management
- Add health/springboot-backend/logpod.sh for backend pod log retrieval and analysis
- Add health/springboot-backend/all.sh for complete build-deploy-monitor workflow
- All scripts include comprehensive kubectl operations, pod recreation monitoring, and log display

ARCHITECTURE REORGANIZATION:
- Move Kubernetes YAML files from k8s/ subdirectories to parent directories for simplified deployment
- Remove deprecated React frontend components (Dockerfile, build.sh, deploy.sh, undeploy.sh)
- Remove nodejs-backend README (consolidated documentation)
- Repurpose React deployment template for Flutter frontend template

INFRASTRUCTURE UPDATES:
- Update Flutter Dockerfile and build scripts for improved container builds
- Update Spring Boot Dockerfile, pom.xml, and deployment configurations
- Enhance HealthDataController.java for better API functionality
- Update build_and_push.sh scripts for both frontend and backend
- Update deploy.sh scripts with improved deployment logic

ENVIRONMENT CONFIGURATION:
- Update financial/.env.example with current configuration patterns

All changes maintain security standards with no hardcoded credentials, only operational scripts and synthetic data.
