Kima-Hub: install the Python services into a uv venv (#17791)

pip3 installed into the system Python with PIP_BREAK_SYSTEM_PACKAGES and
stopped once a dependency wanted a newer idna than Debian's python3-idna,
which pip cannot uninstall (no RECORD file) (#17784). The analyzers now run
from /opt/kima-hub/venv on a uv-managed Python 3.13.
