ENHANCEMENT: Improve multi-platform compatibility for scanner installation

IMPROVED:
- Maldet: Try HTTPS first (secure), fallback to HTTP if needed
- ClamAV: Added explicit Plesk detection and handling
- apt-get: Better package update and installation feedback
- Better error message formatting for Debian/Ubuntu systems
- Improved rpm command error suppression (add 2>/dev/null)

COMPATIBILITY:
- cPanel: Uses cPanel-specific RPM method when available
- Plesk: Now properly detected and uses standard package manager
- RHEL/CentOS: Uses yum package manager
- Debian/Ubuntu: Uses apt-get with proper error handling
- InterWorx: Falls back to standard package manager methods
- Standalone: Works with any available package manager
