Replace `apk update` and `--update` flags with `--no-cache` across Dockerfiles to improve consistency and eliminate unnecessary cache files. This change reduces image size and ensures up-to-date package indices without leaving temporary data. It also aligns with best practices recommended for Alpine-based Docker images.
