ip_analyser 1.0.5

Correct client IP detection for Apache logs that include forwarded address metadata.

- Count the left-most address in the first logged X-Forwarded-For, forwarded_for, or xff field.
- Fall back to the first log field only when forwarded metadata is missing, empty, or '-'.
- Validate IPv4 and IPv6 addresses and skip malformed left-most values instead of counting a later proxy address.
- Reprocess incomplete legacy reports from the beginning so they use the updated parser; completed reports keep their existing results.
- Clarify in report pages that the counts reflect the uploaded log file.
