Subject: [PATCH] GRM-20: fix: skip systemd operations in lifecycle molecule
 when unavailable

The lifecycle scenario runs in a Docker container without systemd
as PID 1. The side_effect and verify playbooks used systemd module
operations unconditionally, causing failures like:

  System has not been booted with systemd as init system

Add a systemd availability check (/run/systemd/system stat) to both
playbooks and conditionally skip systemd tasks when running in
environments without systemd (e.g. Molecule Docker containers).
