CVE-2026-18418 Out-of-bounds read when the zbus proxy agent IPC backend logs a rejected peer frame's channel name

The zbus proxy agent IPC backend in subsys/zbus/proxyagent/zbusproxyagentipc.c logged the channel name of a rejected inter-domain frame with a plain %s conversion. The frame type struct zbusproxymsg carries a fixed-size channelname array as its last member, and nothing in the transport guarantees...
