Asserts that the metadata GraphQL Create + Update mutations correctly
persist and surface `relationTargetFieldMetadataId` on view filters:
- create with relationTargetFieldMetadataId set → returns it on the DTO
- create without it → defaults to null
- update relationTargetFieldMetadataId → new value is reflected on the DTO
- update an unrelated property (value) → relationTargetFieldMetadataId
is preserved (regression test for the universal-identifier-recompute
fix in fromUpdateViewFilterInputToFlatViewFilterToUpdateOrThrow)
Uses the standard Person.company MANY_TO_ONE relation pointing at
Company.name / Company.domainName so the test runs against seed data.
