Fix Dockerfile.baseimage for uv workspace

The base image build also runs 'uv sync --frozen --no-install-project'
but only copies uv.lock + the root pyproject.toml. With the workspace
introduced in this PR, uv needs each member's pyproject.toml to resolve.

Mirror the change made to docker/Dockerfile: copy the workspace member
manifests (but not their source) into the cache layer, switch to
--no-install-workspace, and clean the packages/ dir at the end of the
RUN like we already do for pyproject.toml/uv.lock.
