Proposal: SearchKit show Calculated Field entity refs as joins
Overview
If you join an entity using 'With' then it appears in the 'Add' dropdown as an expandable entity: - see 'Contact Contributions' in this image:
However entities that are joined via Calculated Fields show differently so we get fields like 'Address (billing) Country' rather than a dropdown for Address providing access to all the address fields.
With the recently merged https://github.com/civicrm/civicrm-core/pull/25056, the master_id
field appears in the list but none of its fields.
So can we make those entities show in the same way as those joined via 'With' ? (APIv4 Explorer does this).
