Dashboard 2.0 Mobile access

### Description

[Customer Request](https://app-eu1.hubspot.com/contacts/26586079/record/0-2/6568909041)

When a user’s session/access key expires on a mobile device (specifically using a saved Home Screen icon/link), the dashboard becomes inaccessible ("dead") rather than automatically redirecting the user to the FlowFuse login screen.

In previous versions of the Dashboard, an expired session would trigger a redirect to the authentication provider. Currently, the page remains stagnant or fails to load, requiring the user to manually navigate back to the login URL.

### Which customers would this be available to
