fix(demo): persist login across window close (localStorage) + add Sign out

The token was kept in sessionStorage, which the browser clears when the tab/window closes — forcing re-login every time. Use localStorage so sign-in persists across closes and restarts. Add a "Sign out" control in the header so the persisted token can be cleared on demand (a stale/expired token still falls back to the sign-in screen via the existing /me check).
