Align defaults to Debian 12 and remove the explicit Java setup call from the installer. Updated ct/jitsi-meet.sh to default var_version to 12, json/jitsi.json to reflect version "12", and removed the `JAVA_VERSION=17 setup_java` line from install/jitsi-meet-install.sh so Java is no longer forced by the installer.
