fix(discovery): disable blind updating of IP addresses.

There is no confirmation step done after the address discovery, and
there seem to be cases where the wrong IP address is updated on devices
that temporarily went AWOL.

This feature needs more work to make sure it doesn't update working
addresses to non-working ones.

Issue #5713, possibly also involved in other reports of devices
stopping working soon after startup and not recovering, which users
report as starting in the past 1 or 2 versions rather than from around
2026.4.0 as with other known protocol 3.4 device issues.
