Improve error display with grouping and counting

- Group identical errors and show occurrence count
- Color-code by frequency (HIGH/MEDIUM/LOW)
- Show top 20 most frequent errors instead of all
- Clean up ModSecurity noise (unique_id, pid, tid tags)
- Skip empty error messages
- Exclude FTP logs and bytes_log files from analysis
- Much cleaner output focused on actionable errors
- Answer: Access logs show 5xx errors (500-599), not 404s
