Update Transfer Data project blueprint with new Clickhouse fields

What does this MR do and why?

Contributes to https://gitlab.com/gitlab-org/gitlab/-/issues/442907

Problem

We discovered that the current approach with recording project_path and namespace_path in logs has a flaw.

It's possible for clients to update the path of their groups and projects: https://docs.gitlab.com/ee/user/group/manage.html#change-a-groups-path. It means that after update we will lose a connection between old and new records in Clickhouse.

Solution

Use project_id and root_namespace_id because they are immutable and won't be affected by the project/group path changes.
