Secure Authentication and Role-Based Access Control via Zustand

Act as a Frontend Security Architect. Design a highly secure authentication slice within Zustand explicitly for a sensitive e-commerce admin panel. Strictly define the [USER_ROLES] (e.g., SuperAdmin, Editor, Viewer) and securely store their hashed permissions in state. Implement an automated [TOKEN_REFRESH_STRATEGY] that natively interacts with an Axios interceptor to silently update the JWT within the Zustand store before expiration. Engineer an infallible [AUTO_LOGOUT_TIMER] that forcefully purges the entire Zustand authentication state and triggers a React Router redirect to the login screen after exactly 15 minutes of mouse/keyboard inactivity. Guarantee the 'auth' state is heavily obfuscated and logically isolated so it cannot be easily manually manipulated via the browser dev-tools console.
