feat: Prepare Zemailnator for Dokploy deployment

- Add highly optimized Dockerfile with Nginx and PHP-FPM 8.4
- Add docker-compose.yml configured with Redis and MariaDB 10.11
- Implement entrypoint.sh and supervisord.conf for background workers
- Refactor legacy IMAP scripts into scheduled Artisan Commands
- Secure app by removing old routes with hardcoded basic auth credentials
- Configure email attachments to use Laravel Storage instead of insecure public/tmp
