Fix: Scan logs in subdirectories to catch all domain errors

Issue: Was missing 500 errors from logs stored in subdirectories like
/var/log/apache2/domlogs/username/domain.com

Changed from simple glob (domlogs/*) to recursive find command that:
- Scans all files in domlogs directory AND subdirectories
- Excludes system files (bytes_log, offset, error_log, ftpxferlog, ssl_log)
- Finds ALL domain access logs regardless of location

This ensures we catch errors like "GET /ay.php HTTP/1.1" 500 that were
previously missed in subdirectory logs.
