Add Plesk log path documentation based on official research

RESEARCH CONDUCTED:
Consulted official Plesk documentation to verify log paths:
https://docs.plesk.com/en-US/obsidian/

VERIFICATION:
Current code is CORRECT - uses wildcard pattern that catches all Plesk logs:
- Apache HTTP: access_log
- Apache HTTPS: access_ssl_log
- nginx HTTP: proxy_access_log
- nginx HTTPS: proxy_access_ssl_log

DOCUMENTATION ADDED:
- Added official Plesk log paths in comments (lines 310-318)
- Noted hardlink relationship between /var/www/vhosts/{domain}/logs
  and /var/www/vhosts/system/{domain}/logs
- Updated domain extraction comment for clarity (line 334)

No code changes needed - existing wildcard pattern already works correctly.
