PHASE 2: InterWorx bot-analyzer support + firewall detection

BOT-ANALYZER INTERWORX SUPPORT:
This is the CRITICAL missing piece for InterWorx servers!

1. Log File Discovery (bot-analyzer.sh:1769-1830)
   - InterWorx stores logs at /home/user/var/domain.com/logs/access_log
   - NOT in centralized /var/log/apache2/domlogs like cPanel
   - Added special detection when SYS_CONTROL_PANEL=interworx
   - Searches for all access_log files across all domains

2. Parse Logs Function (bot-analyzer.sh:281-338)
   - Added INTERWORX_MODE flag for special handling
   - InterWorx: extract domain from path (/home/*/var/DOMAIN/logs/)
   - cPanel: extract domain from filename (domain.com or domain.com-ssl_log)
   - Unified log parsing with control panel-specific domain extraction

SYSTEM-DETECT.SH IMPROVEMENTS:

3. Fixed InterWorx Log Directory (system-detect.sh:70-73)
   - Old: SYS_LOG_DIR="/home" (WRONG - too generic!)
   - New: SYS_LOG_DIR="/home/*/var/*/logs" (marker path)
   - Tools recognize this pattern and apply special handling

4. Added Firewall Detection (system-detect.sh:268-337)
   - Detects: CSF/LFD, firewalld, iptables, UFW
   - Exports: SYS_FIREWALL, SYS_FIREWALL_VERSION, SYS_FIREWALL_ACTIVE
   - Special export: SYS_CSF_ACTIVE (for CSF-specific tools)
   - Integrated into initialize_system_detection()

IMPACT:
- bot-analyzer now works on InterWorx servers!
- Discovers per-domain logs correctly
- User filtering (-u flag) works with InterWorx
- Firewall detection enables future automation features

TESTING:
- All syntax validated with bash -n
- Ready for testing on actual InterWorx server
