Subject: [PATCH] feat(media-supply): resource cache sync and order flow
 refinements

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.
