fix: improve dockcheck cron job logging and reliability

- Added comprehensive logging to /var/log/dockcheck/dockcheck.log
- Created wrapper script to avoid cron variable escaping issues
- Added timestamp logging for each execution with exit codes
- Created proper log directory with correct permissions
- Removed unnecessary -n flag (config file handles DontUpdate=true)
- Added cron handlers for service management
