fix(pipeline): thread KS2 progress CI columns through the legacy union and lineage model

The AI review gate caught that stg_ees_ks2's 7 new columns broke the
positional UNION ALL with stg_legacy_ks2 in int_ks2_with_lineage, and
that the lineage CTEs never emitted them (same class of bug fixed for
KS4 in 34a5de2). Legacy gets typed null placeholders at matching
positions; both lineage CTEs pass the columns through. 45/45 columns
verified name-identical in order across both union branches.
