migration 098: allow compliance order types in order_audit_log

The admin compliance-orders approve/re-arm actions write order_audit_log rows
with order_type='compliance', but the CHECK constraint (from migration 004)
only allowed formation/service/quote -- so every approve failed with a 500
('Approve failed.'). Expand the constraint to include compliance + compliance_batch.

+-- 098: Allow compliance order types in order_audit_log.
+--
+-- order_audit_log was created (migration 004) for formation orders only, with a
+-- CHECK constraint limiting order_type to ('formation','service','quote'). The
+-- admin compliance-orders dashboard writes audit entries for compliance orders
+-- (approve-for-submission, intake re-arm), which were rejected by that check and
+-- surfaced as "Approve failed" 500s. Add the compliance order types.
+--
+-- Idempotent: drops and recreates the constraint with the expanded value set.
