feat(users): implement user management features and database schema

Added user management functionality, including the creation of app_users and user_interface_bindings tables in the database. Implemented API routes for user data retrieval and permissions handling. Enhanced the traffic monitoring system to include user traffic statistics and interface bindings. Updated relevant components and services to support the new user features, improving overall application functionality and user experience.
