Three small fixes from the final review:
- AbsenceAdmin.save_model() now runs _sync_absence_payroll_adjustment
so toggling is_paid via /admin/ updates the linked Bonus consistently
with the friendly UI.
- _delete_adjustment_with_cascade clears absence.is_paid when deleting
a Bonus linked to an Absence — closes the state-drift window after
bulk-delete from /payroll/?status=adjustments.
- base.html — Resources dropdown 'Absences' entry now shows for
supervisors as well as staff (was staff-only). View-layer permission
helpers (_absence_user_queryset, _user_can_log_absences) already
enforce the real access boundary; this just makes the menu honest.
2 regression tests.
