refactor: reorganize project structure for better maintainability

- Move Docker files to build/docker/
- Move CI/CD configs to build/ci/
- Move deployment configs to deploy/ (helm, k8s, argocd)
- Move config files to config/
- Move scripts to tools/
- Consolidate assets to assets/ (Reflex compatible)
- Add data/ directory for local data (gitignored)
- Update all path references in Makefile, Dockerfile, CI configs
- Add comprehensive README files for build/ and deploy/
- Update project documentation

Benefits:
- Clear separation of concerns
- Cleaner root directory
- Better developer experience
- Enterprise-grade structure
- Improved maintainability
