space_server: bird: duplicate customer sessions

Duplicate all customer BGP sessions, so that there
is one with the old prefix, and one with the new one.

This enables everyone to migrate to the new IP addresses
at their own pace.

Once the migration has been completed, we will remove the
old sessions.

Applied on 2025-04-25.
