VERIFY: API - Manually affiliate all existing NRs

- [ ] Need to update the API to allow all NR entity types to be affiliated to the Manage Business Dashboard

This may be already done when we implemented auto-affiliate NR to the MB dashboard. It will be a verify ticket.

Start by reviewing the API behavior related to auto-affiliating NR entities to the Manage Business Dashboard. Verify whether every NR entity type can be affiliated, and check any existing coverage for this behavior. Done means confirming that the requested support already exists or documenting the missing entity types and required follow-up.
