I prepared a new EPICS ca-gateway server (Debian 13) to replace the current ca-gateway server, which has become a legacy system.

Since the EPICS base and EPICS extensions for Debian 13 had been already built as described in klog#35372 and klog#37207, they will be used.
Details on server setup can be found in JGW-T2617453.

The major changes are the OS upgrade (Debian 8 → Debian 13) and the migration of managing ca-gateway process to systemd. This will automate process startup during server reboots and a recovery from some trouble, and ensure that process logs are properly managed. This server is currently in standby mode between the DGS network and the virtual network and is planned to be swapped with the current server on the next maintenance day.
