Switch to maven-dependency-plugin and adjust build output

Replaced `maven-shade-plugin` with `maven-dependency-plugin` for dependency management, simplifying the build process and separating runtime dependencies into a dedicated `lib/` directory. Updated `Dockerfile` and GitHub Actions config to account for these changes, ensuring all dependencies are correctly packaged and deployed.
