Implement updateSubscription feature and refactor billing services

This commit introduces the updateSubscription method to the BillingStrategyProviderService, ensuring that subscriptions can be updated within the billing core. Additionally, a refactor has been applied to the BillingGatewayFactoryService and stripe-billing-strategy.service to improve error handling and the robustness of subscription updates. Logging in the webhook route has been adjusted for clarity and the data model has been enhanced.
