The controller implements `cabana.AdminRelationContractProvider` and returns a `cabana.RelationContract` per relation: the related and pivot model factories, the pivot's two foreign keys, a map from column names in the YAML to physical columns, and optionally the pivot columns a hook may set and a function that excludes candidate IDs, such as the parent itself. A relation in the YAML without a contract, a contract without a relation, or a relation without a `relation-manager` field stops the start-up.
`cabana.RelationService` serves the panels: linked records, link candidates, link and unlink, under `.../{id}/relations/{name}`. Link and unlink run in a transaction. `pact.RelationExtendManageQuery` scopes the candidates, and `pact.RelationBeforeLink` can check or fill pivot columns before a link is written.
`cabana.RelationService` serves the panels: linked records, link candidates, link and unlink, under `.../{id}/relations/{name}`. Link and unlink run in a transaction. The `view` panel's `toolbarButtons` decide which of the two the server accepts: a relation that does not list `unlink` answers 403 `forbidden` on the unlink route, and likewise for `link`. `pact.RelationExtendManageQuery` scopes the candidates, and `pact.RelationBeforeLink` can check or fill pivot columns before a link is written.
