chore: Refactor CI workflow for Docker builds to include shared setup job

### Summary of Changes
- Introduced a shared setup job in the CI workflow to streamline common steps for building and pushing Docker images.
- Updated individual build jobs for API Gateway, Service Adapters, API Docs, and Frontend to depend on the setup job, ensuring consistent versioning and labeling.

### Expected Results
- Enhanced maintainability and clarity of the CI workflow by reducing redundancy and centralizing setup steps, leading to more efficient Docker image builds.
