Moskee Backend Api

Create a modular, feature-based backend API using Express.js in JavaScript. I need the structure to be highly maintainable, following the Single Responsibility Principle. The core setup should initialize the Express app, set up middleware like CORS and JSON parsing, and handle central error management. Please ensure the architecture cleanly separates concerns by using dedicated directories for routes, services, and utilities. Specifically, I need to integrate Supabase for authentication, using a dedicated service to initialize the Supabase client from environment variables, and I also need to handle Stripe integrations by initializing the Stripe client. The main entry point should orchestrate the setup and connect all feature routers.
