Add TableRelation field-length and RecordRef.Open Temp knowledge

- data-modeling: tablerelation-field-length-must-match-related-field
  (exact length for unconditional relations, at least the longest target
  when all relations are conditional; no compile-time diagnostic)
- testing: recordref-open-temp-parameter-defeats-real-table-checks
  (a temp-opened RecordRef is empty, so existence/uniqueness checks on it
  never see persisted rows; cross-links use-generateguid article)
- Wire both into the review leaves and register the fixture pairs.
