The three pending migrations have been applied, so absence_type exists and
the workaround that kept it out of this select can go. The status chip in
the list shows the specific kind again ("Bildungskarenz" rather than the
generic "Langzeitabwesenheit"), matching the detail page.
Verified against the database rather than by typecheck: employee_assignments
holds 809 rows for 809 employees with exactly one open interval each,
is_valid_svnr() agrees with the TypeScript implementation on all nine
documented cases, and the list, org-chart and detail queries all return rows.
