fmtIP() returns an HTML <a> tag string. Using encodeURIComponent(fmtIP(ip))
was URL-encoding the entire HTML markup instead of the raw IP address,
resulting in /ip/%3Ca%20href%3D... navigation.
Fix: extract raw IP (stripping ::ffff: prefix) before building the URL.
Applied to all 3 click handlers in campaigns.html:
- members table row onclick
- scatter chart point click
- force graph node click
