Subject: [PATCH] fix: print machine ID hash and mount /etc/machine-id for
 offline .lic binding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

install.sh now computes and displays the SHA-3-256 hash of /etc/machine-id
at the end of every run so the customer can share it with the vendor when
requesting an offline .lic bound to this host. The hash is stable — it
never changes after OS installation, so re-running install.sh or restarting
the container will always show the same value.

compose.yaml now mounts /etc/machine-id:ro into the manage-server container
so ReadMachineID() can verify the offline .lic binding at startup.
