- sync-scheduler.ts: extend sync_type union with 'tickets-reconcile', add a
default schedule entry (disabled, 30 4 * * *), and a dispatch case using
the device-link-reconcile / integration-health dynamic-import pattern.
- migrations/090_ticket_reconcile_schedule.sql: idempotent INSERT (ON CONFLICT
DO NOTHING) so existing installs pick up the row without disturbing the
fresh-DB default-seed path.
