2 AL/BC patterns: TableRelation field length and RecordRef.Open Temp parameter (#208)

* 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.

* Address review: TableRelation validation carve-out, RecordRef nits

- tablerelation: fields with ValidateTableRelation/TestTableRelation = false
  are skipped by codeunit 134926 and may be longer (filter/totaling
  fields); shorter is still a finding. Add Code/Text type rule, BaseApp
  evidence, a ValidateTableRelation = false filter field to the good
  fixture, and the carve-out to the data-modeling cue.
- recordref: add FindLast/Next, relabel SplitLocalTableFilter as filter
  splitting, mark fixtures as test-library-style helpers.

* Drop unverified claim about where-filtered relations

The Table Relations Metadata mapping of where(...) filters to
Condition Field No. is not documented and could not be verified; the
rule does not depend on it.
