feat: updates legacy libraries list API to include migration info [FC-0097] (#37286)

Adds migration info like `migrated_to_title`, `migrated_to_key` and `is_migrated` fields indicating whether the legacy library was migrated to library v2. If yes, it includes the new library name and key.

Users can also filter by migration status using `is_migrated` query param.
