* fix: return client IPv6 address via cloudflared
The cloudflared reverse proxy populates the X-Forwarded-For header for origin IPv4 addresses, however origin IPv6 addresses are added in a different header: Cf-Connecting-Ipv6. This updates the getIP.php mechanism to retrieve the value of this header and to prefer it over other client IP headers (in both cases only if the Cf-Connecting-Ipv6 header exists and is not empty).
* fix: Validate and normalise IP addresses from request headers
getClientIp() used HTTP_CF_CONNECTING_IPV6 and other headers verbatim, allowing malformed values to reach ISP lookups and the offline DB.
Add normalizeCandidateIp() helper that trims whitespace, extracts the first comma-separated token, and validates via filter_var(). Require FILTER_FLAG_IPV6 for the CF header and fall through to the next source on failure.
Written with assistance from OpenCode using Claude Opus 4.6.
