Status line builds the wrong status items in offline mode

this happens because the `currentScreen` variable that the StatusLine class uses to call `currentScreen.buildStatus(context)` is a `SimpleScreen` and not the screen type for the data (e.g. `PerformanceScreen`, `NetworkScreen`, etc.).

Start by tracing the StatusLine class and its use of currentScreen.buildStatus(context) while offline. Compare the SimpleScreen instance with the relevant data screens, such as PerformanceScreen and NetworkScreen, and confirm that the status items are built for the active screen type; done means offline mode shows the correct status items.
