Add new type definitions to billing/core package

New type definitions have been added to the billing/core package: UpsertOrderParams and UpsertSubscriptionParams. These types were then exported and used in other services, removing duplication and ensuring type consistency across the package. The changes have been reflected in the package.json file of billing/core package.
