As per suggestions by IDEA. I didn't update Dagger, though, since this
could break some APIs we're using.

Faking online states with an
```kotlin
isConnected = Random.nextBoolean()
```
in `ContactItem` ;)

As per
!174 (comment 63629).

Thanks to the research of Paul, I could quickly find the right modifier
to change the mouse appearance upon hovering buttons.

For most buttons we stay with the default PointerIcon, just inside text
fields it showed the text PointerIcon. With this commit the default
PointerIcon is shown consistently across all buttons.

In a later MR we could switch all buttons to show the hand icon, but I
wouldn't do it because later Compose versions might do this
automatically and the APIs used here are experimental.

I added the correct `Locale` as a parameter to all usages of `uppercase()`.

There are only two usages of `lowercase()` that don't need no `Locale`:
* when selecting the keys in the theme dropdown
* when checking the extensions of images
