Original Pull Request: https://github.com/netbirdio/netbird/pull/5839

State: closed
Merged: Yes

Describe your changes

Address CodeRabbit review comments from #5631.

Anonymize AddressV6 in debug bundles, preserving the original prefix length
Anonymize IPv6 ULA addresses in debug bundles (the 40-bit global ID is a network fingerprint, unlike RFC 1918 IPv4 which is reused everywhere)
Fix data race on extraListeners in SSH server Stop() by snapshotting under mutex
Warn and clear IPv6 on Windows when IPv6 MTU setup fails, matching Linux/macOS behavior
Clear stale DNS settings from the opposite address family in NetworkManager configurator
Check AddPeer errors in status test setup instead of discarding them

Issue ticket number and link

Follow-up to #5631
