feat: enhance window switching by focusing on second preview

- When classic ordering is enabled and there are at least two windows,
  set the initial focus on the second window preview instead of the first.
- This improves switching speed and provides a more intuitive experience,
  similar to Windows OS behavior.

- Fixes ejbills#455 ejbills#439 ejbills#431
