feat: improve Docker setup, publish to GHCR, and enhance test client

- Add --allow-net to Dockerfile CMD for Deno network access
- Add .dockerignore to reduce image size and exclude unneeded files
- Update GitHub Actions workflow to publish to GitHub Container Registry (GHCR)
- Improve integration test client with assertions for automated validation
