test(views): regenerate canonical schema for the unified view emitter

The single emitViewDdl emitter renders aggregate views as one LEFT JOIN +
GROUP BY (COUNT(DISTINCT) to survive the join), whereas the deleted
migrate-ts emitter used correlated subqueries. The two are data-equivalent
for a single has-many join — pinned by the projection-aggregate query
scenarios (populated rows + the empty-program NULL case), which pass
against real Postgres.

Regenerate the committed canonical schema.postgres.sql (bun run gen:schema)
and update the schema-artifact Phase B assertions from the correlated-
subquery form to the JOIN+GROUP BY form. Also reflects view-body identifier
quoting + strategy-resolved JOIN columns.
