feat: add dynamic versioning and automated deployment with rollback capability

- Implement setuptools-scm for dynamic version management from git tags
- Refactor CI/CD into separate build and deploy jobs with artifact sharing
- Add versioned releases with timestamp-based deployment directories
- Implement health checks and automatic rollback on deployment failure
- Extract deployment logic into reusable shell scripts
- Add Docker layer caching to speed up builds
- Include version info in Django context and build args
