Update Dockerfile and remove unnecessary import

Removed unused import `Status::Success` in `src/lib.rs` file, providing clearer code structure. Updated Dockerfile by including cbindgen installation and configuration. This change allows the generation of C bindings for Rust code to create a header file for the application, improving compatibility with C applications.
