feat(mailctl): Add daily report and fix port status check

- Port status now checks inside container (not localhost)
- Added report command: generate, send, enable, disable
- Daily report includes server status, mail queue, logs, storage
- Cron job setup for automated daily reports at 7 AM
- Report sent to admin_email configured in UCI
