DEV: Ensure unique notification level per tag user (#28638)
TagUser.rb is used to set user notification levels for a tag, we don't have a unique index on the notification level itself. This means that there might be some weird case where a user may have multiple of the same notification level on a tag.

This PR adds a migration which de-duplicates this based on defaults, where we keep the earliest record in the event there is multiple notification level per-user-per-tag.
