Refactor application to MVC architecture with Flask blueprints
Major architectural refactoring to improve code organization, maintainability, and scalability: - Implement MVC pattern with clear separation of concerns - Organize code into blueprints for different functional areas (main, tenant, admin, api) - Create models layer to encapsulate all database operations - Create services layer for business logic (auth, product, barcode) - Implement application factory pattern for better testability - Add environment-based configuration management - Remove old monolithic app.py and consolidate routes New structure: - app/models/ - Database operations (Tenant, Product, ARField, Settings) - app/services/ - Business logic (Auth, Product, Barcode services) - app/blueprints/ - Controllers organized by function - app/config.py - Environment configurations - run.py - Application entry point All routes remain backward compatible. No changes to API or templates functionality.
