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.
Introduce an end-to-end media-supply feature: tenant-side resource sync
service/worker backed by a Meijiequan supplier client, ops-side management
APIs, and admin/ops web views for resources, orders, favorites and
submission. Adds a shared digitocr helper, MediaSupply config blocks for
tenant and ops, shared types, and migrations for supplier media resources,
price overrides, customer visibility and order refunds.
