Add a resource cache sync entrypoint (RunMediaResourceSyncOnce) driven by the new scheduler job, and rework the backlink/sync worker around it. Tune the meijiequan client and slow the default backlink sync interval from 10m to 30m to reduce upstream pressure. Trim unused public/transport surface (handler + router + swagger) and simplify admin-web order management and ops-web media-supply views, dropping stale shared-types fields.
