Use the right insets in the home screen UI (#7271)

* Use the right insets in the home screen UI

That's `WindowInsets.statusBar` for the `Scaffold` component, then `WindowInsets.navigationBar` for the `LazyColum.contentPadding`

* Apply it to other screens with long lists of items too

* Apply the insets to `PreferencePage` too

* Apply inset changes to other screens with scrollable content

* Add helper insets/padding values based on review suggestions.

* Use the newly added insets/padding values in several scaffold and scrollable columns
