Update Dockerfiles to use bytelyst-common-base-backend and bytelyst-common-base-web
images instead of installing @bytelyst/* packages via tarballs.
Benefits:
- Smaller final images (~50MB vs ~250MB)
- Faster builds (base image cached)
- Consistent package versions across products
- No need for docker-prep.sh tarball packing
