feat: replace Kaniko with buildah for container builds

- Switch from archived Kaniko to actively maintained buildah
- Use buildah from Alpine repos (no manual binary downloads)
- Replace bash syntax with POSIX sh (case instead of [[ ]])
- buildah works better in unprivileged containerized environments
- Simpler setup: just apk add buildah, no extra configuration
