Add IP filtering and reorganize Website Management menu

IP Filtering enhancements to 500 error tracker:
- Filter localhost/internal IPs (127.x, 10.x, 172.16-31.x, 192.168.x)
- Detect cloud scanner IPs from AWS, GCP, Azure with user agent validation
- Skip known bot network IP ranges to reduce noise
- More aggressive filtering of non-relevant traffic

Website Management menu reorganization:
Reduced from 16 options to 7 logical categories:

Main menu now has:
1. Website Error Analyzer
2. Fast 500 Error Tracker
3. Debug Log Analyzer
4. Health & Maintenance → (5 tools: health check, DB optimizer, cache, plugin/theme audit)
5. WP-Cron Management → (3 tools: status, mass fix, system cron setup)
6. Mass Updates → (3 tools: core, plugins, themes updates)
7. Security & Compliance → (3 tools: malware scanner, permissions, login audit)

Benefits:
- Cleaner, more organized menu structure
- Related tools grouped together
- Easier navigation with logical subcategories
- Reduced cognitive load (7 vs 16 options)
