Subject: [PATCH] fix(gateway): skip systemd check when systemctl is absent

`supports_systemd_services()` unconditionally returns `True` on Linux,
but Docker containers typically lack systemd/systemctl. This causes
`hermes gateway setup` to crash with a `FileNotFoundError` when it
tries to invoke `systemctl is-active`.

Guard with `shutil.which("systemctl")` before assuming systemd support.
