Replace direct MarketPlace imports with MarketService calls

Market CRUD in blog now delegates to services.market.create_marketplace()
and soft_delete_marketplace() instead of importing MarketPlace directly.
Adds TODO comments on Calendar imports in admin routes (deferred to
admin UI rework). Updates shared submodule.
