feat: use registry cache for faster builds

- Add xingrin-postgres image build job to docker-build workflow for multi-platform support (linux/amd64,linux/arm64)
- Update docker-compose.dev.yml to use IMAGE_TAG variable with dev as default fallback
- Update docker-compose.yml to use IMAGE_TAG variable with required validation
- Replace hardcoded postgres image tag (15) with dynamic IMAGE_TAG for better version management
- Enable flexible image tagging across development and production environments
