chore: Refactor Dockerfile and build workflow for improved efficiency

- Removed the build stage from the Dockerfile, simplifying the image creation process.
- Updated the Dockerfile to directly copy the pre-built binary instead of using a multi-stage build.
- Modified the build workflow to eliminate unnecessary build arguments, streamlining the configuration.
