Update and refactor billing services and types

Several updates and refactorings have been made to the billing services and types. The "onInvoicePaid" method and some types related to line items have been removed. The comments and arguments for the "verifyWebhookSignature" and "handleWebhookEvent" methods in service classes have been updated for clarity. The "onEvent" method's arguments have also been adjusted in multiple places to improve consistency.
