Add trigger-default and declined-Confirm knowledge with review cues

Three Microsoft-layer articles with good/bad samples:
- error-handling/declined-confirm-must-abort-not-partially-apply
- data-modeling/delete-master-data-with-trigger
- data-modeling/master-data-must-be-inserted-with-trigger

Wire targeted worklist cues into al-error-handling-review and
al-data-modeling-review and register the samples in review-fixtures.json.
