Describe your changes

Exclude disconnected or uninitialized peers when building DNS records for a network map. This prevents DNS routes from continuing to advertise stale addresses after ephemeral routing peers are replaced.

Summary by CodeRabbit

Bug Fixes
- DNS record filtering now ignores peers that aren’t currently connected, so only reachable peer addresses are considered.
Tests
- Added a unit test to confirm disconnected peers are excluded from filtered DNS results.
- Updated DNS test setup to ensure peer connectivity status is persisted before DNS-related assertions run.
