- Encryption::generateUniqueCode(): null-coalesce $pass to prevent
md5(null) deprecation when live_streaming_pass is not yet set
- CacheCronJob: mkdir() with 0755 perms, recursive flag, and
chown to xc_vm user — fixes Permission denied on tmp/cache/*
- WatchdogCommand: null-safe decode of watchdog_data — fixes
array offset on null when server has no watchdog history
- ConnectionTracker: guard file_put_contents with is_dir() check
to prevent writes when CACHE_TMP_PATH does not exist yet
- Dockerfile: install cron package and enable cron.service for
systemd-based test container
