nicandClaude Opus 5.5 07179d7eae fix: set the WS-Discovery probe's interface before sending (#5257) ...

WSDiscovery::TransportUDP::send_multi opened its socket with PeerAddr,
which connects it, and called mcast_if afterwards. A connected UDP
socket keeps the route chosen at connect time, so on a host with more
than one network the Probe left through the default route whatever
interface was chosen: the web UI's ONVIF probe (zmonvif-probe.pl probe
<version> <interface>) found no camera on a second network.

Open the socket unconnected, set mcast_if first, and send to the group
with mcast_send. The destination is passed as a packed sockaddr_in:
given as "addr:port", mcast_send in IO::Socket::Multicast 1.12 (Debian
trixie) ends up with port 0 and the send fails with EINVAL. Without an
interface nothing changes: the probe goes out the default route as
before.

tests/perl/test_wsdiscovery_mcast_if.pl records the socket calls and
checks the order and the destination.

fixes #5256
