Subject: [PATCH] Add Stripe integration for customers, payments, and products

This commit introduces a comprehensive Stripe module with support for managing customers, products, prices, and payment links. It also includes endpoint routes, helpers, and database updates to support Stripe operations, such as creating and retrieving entities or handling payment workflows. Additionally, a stripe module was integrated into existing routes and objects to enable seamless interaction with Stripe APIs.
