feat(media-supply): add media resource supply marketplace

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.
