Printers added to Bambuddy by hostname/FQDN (e.g. p1s.fritz.box) hit
'invalid IPv4' in _ip_to_uint32_le, so the net.info[*].ip rewrite never
armed and BambuStudio Send went straight to the real printer instead of
the Bambuddy archive whenever the printer was powered on.
Add _resolve_target_to_ipv4(target): IPv4 pass-through, else
socket.getaddrinfo(target, family=AF_INET). AF_INET filter is load-bearing
because net.info[*].ip is uint32 LE and IPv6 can't round-trip. OSError
returns None so a transient DNS failure recovers on the next 30s refresh
tick via the existing not-armed throttle.
Apply the resolver to both the encode call and the host-interface picker
(which also assumes dotted-quad). Armed log line now carries
configured->resolved when they differ, so bad-DNS regressions stay legible
in 'docker logs'. The unresolvable not-armed reason now names the
configured value rather than parroting 'invalid IPv4', distinguishing
'DNS gave a v6 result' from 'user typed garbage'.
Root-caused by @Mape6; @TrickShotMLG02 confirmed the FQDN workaround
on the same release. Pre-0.2.4 these setups worked by accident because
there was no net.info[].ip rewrite at all.
