fix: correct Docker migration service configuration

- Fix ackify-migrate service to run migrate binary instead of main server
- Add entrypoint override to bypass default ENTRYPOINT in Docker image
- Copy migrations directory to Docker image for migrate binary access
- Update migrate binary with better error handling and code quality
