Web UI refactor client login/change with pulling storage configuration

[nopcoder]

The current web UI login uses a provider to manage global state with server-side storage configuration. Client information is cached in local storage.

The main issue with the current code is that login/logout does not notify or update the provider, preventing re-triggering of changes and pulling the latest storage information.

As a workaround, the code currently reloads the page after login.
