Since #4866, hostnames in webrtcAdditionalHosts are resolved server-side via
net.LookupIP, and a resolution failure aborts the entire WHEP/WHIP session.
A single entry that can't be resolved on the server (e.g. air-gapped networks
without DNS, or a name that only resolves on the client) therefore takes down
all WebRTC playback, even when the other entries are valid.
Log a warning and skip the unresolvable entry instead of returning an error,
so the remaining valid candidates are still offered.
