Same class of cross-file test-isolation gap already fixed in
orchestration-flow.test.ts and sla-escalation-flow.test.ts (010's own
regression work): a wildcard (non-product-scoped) SLA policy from
another suite can match this file's own tickets too, leaving a real
sla_run row that RESTRICTs the ticket delete. Also cleaned up several
orphaned wildcard SLA policies that had accumulated in the shared
throwaway test database from earlier runs.
