Fix pyright type errors across codebase

- Add pyrightconfig.json for pyright 1.1.408 TOML parsing workaround
- Add NoReturn annotations to fatal() functions for proper type narrowing
- Add None checks and assertions after require=True get_record() calls
- Fix AttrDict class with __getattr__ for dynamic attribute access
- Add type annotations and casts for Kubernetes client objects
- Store compose config as DockerDeployer instance attributes
- Filter None values from dotenv and environment mappings
- Use hasattr/getattr patterns for optional container attributes
