IMPLEMENT: Standalone server domain and log discovery

FEATURE: Domain Discovery for Standalone Servers
- Added get_standalone_user_domains() function
- Parses Apache VirtualHost configs (/etc/apache2, /etc/httpd)
- Falls back to checking domain directories in user home
- Returns sorted list of unique domains

FEATURE: Log Discovery Implementation
- Implemented build_logs_section() for log file discovery
- Standalone: Find access/error logs in log directory
- Nginx support: Find logs in /var/log/nginx
- Safety limits: 30-day files, max 50 per type, max depth 2
- Prevents hangs on large log directories

BENEFITS:
✅ Standalone servers now discover domains
✅ Standalone servers now discover logs
✅ malware-scanner can now run on standalone
✅ website-error-analyzer can now run on standalone
✅ live-attack-monitor can now run on standalone
✅ log-tailing tools now work

SAFETY:
- Limited to recent files (mtime -30)
- Limited search depth (maxdepth 1-2)
- Limited result count (head 50)
- No regex hangs from large directory scans
