extractUdpPort: handle Komodo's newline-string ports form

Real Komodo GetDeployment responses render config.ports as a single
newline-delimited string ("28963:28963/udp\n28963:28963/tcp\n"), not as
the array shapes we already handled. The walker only descended into
arrays and objects, so the string was skipped entirely and every Komodo
probe on a real deployment fell through to no-udp-in-response.

When the walker hits a value under a ports-keyed field that's a string,
split it on \r\n , ; and treat the resulting parts as a preferred string
array — the existing "host:container/udp" and "container/udp" regexes
handle each part.

Fixture pulled verbatim from the t5-nacht-1 response the fleet UI
surfaced. Also covers single-line, host-network (no host prefix), and
TCP-only-shouldn't-match cases.
