Legacy deployment samples removed

The Docker, Compose, Nginx, SQL, and Kubernetes samples previously stored in this directory were removed because they invoked nonexistent example distribution tasks and configured legacy JWT, password-session, and raw-IP behavior. They are not compatible with the Aether Identity 0.6.0.0 release.

For the passkey authority, follow only the Aether Identity deployment guide. For an unrelated aether-core application, own the application image, configuration, secret model, observability policy, and orchestration manifests in that application repository.
