fix(host/logs): mdns-sd noise gate + tracing-log target normalization in the log ring

log-crate events arrive through the tracing-log bridge under the shim target
"log" — normalize them back to the real module path (NormalizeEvent) so the
console's target column and the noise gate see mdns_sd::… , and suppress the
bridge's log.* bookkeeping fields like the stderr fmt layer does.

Gate known-chatty third-party DEBUG targets (mdns-sd DEBUG-logs every
unparseable multicast packet — one AirPlay device floods thousands of entries
per hour) to INFO-and-up in the ring, so ambient LAN noise can't evict the
tail the ring exists to preserve. stderr under RUST_LOG is unaffected.
