Add automated multi-scanner support and result comparison

New Features:
- 'All Available Scanners' option in all scan modes (server/user/domain/custom)
- Runs ImunifyAV, ClamAV, and Maldet sequentially with progress tracking
- Creates consolidated multi-scanner session reports
- Shows [1/3], [2/3], [3/3] progress indicators
- 3-second wait between scanners to prevent system overload
- Session reports saved to logs/malware-scans/multiscan_*.txt
- Stores session IDs in reference database for cross-module access
- New 'Compare scanner results' option (menu option 6)
- View consolidated reports from multiple scanners

Workflow:
1. Select any scan scope (server/user/domain/path)
2. Choose 'All Available Scanners' option
3. All installed scanners run automatically one after another
4. Single consolidated report with all results
5. Use option 6 to compare/view latest multi-scanner session

Much more automated - no need to run each scanner separately!
