Account details dialog improvments
The account details
- say "Preferences", would likely be nicer to say "Edit account" or "Account details"
- the "delete" button is in a very prominent place and doesn't have the "destructive-action" class
- The device ID is hidden behind "Advanced Information" although it is needed to verify to the other side of an encrypted chat
- device id, matrix id and home-server aren't selectable
- The status is indicated as "connected" but can't be changed
/cc @tobias.bernard so i'm not suggesting outdated/wrong stuff
