refactor(ip-parsing): centralize multi-delim splitting in splitIps

Extend splitIps to accept comma/semicolon/newline delimiters with dedupe,
and reuse it in DetailPanel for both the IP list and the service-URL host.
Fixes ServiceBadge links pointing at concatenated string when IPs were
entered with ';' or newline separators. Adds tests for new delimiters.
