fix(logout): clear Inertia prefetch cache on logout to prevent data leakage. (#97)

Ensure the `router.flushAll()` method is called during the logout process to clear the Inertia prefetch cache.
This prevents potential data leakage where a later user on the same device could access preloaded data from the previous session.
