Add plogical/cyberpanel_python.py with resolve_cyberpanel_python() and ensure_cyberpanel_bin_python_shim() (symlink to system Python when venv binary is absent). Call shim before writing root crontab on install/upgrade, and from IncBackups/IncScheduler.py so existing jobs self-heal. IncBackups views use resolved interpreter for backupUtilities. Upgrade._python_for_manage delegates to resolve_cyberpanel_python().

Some installs omit /usr/local/CyberCP/bin/python (no venv). We symlink that path
