- handle contact PATCH failures by checking model save result and returning HTTP 400 with the model error message
- update ContactDetailModel nested updates to enforce active-detail checks and use model update() with explicit failure propagation
- extend contact patch assertions and align test-create variants expectations to status=success for POST responses
- refresh composer lock metadata/dependency constraints and include generated docs/data/test files updated during normalization
- impact: API contract unchanged except clearer 400 error responses on invalid contact detail updates
Use the base test row's RefType and ResultType to decide refnum/reftxt loading, and fetch discipline/department joins directly in getTestById to avoid redundant relation queries. Add feature coverage for show response behavior and include the related workspace cleanup changes so the branch state is consistent.
