more sane diagnostic picker column ordering

this fixes #12571

now it looks like this:

Would be nice if it got added to the next patch release: #12560

The current ordering is intentional: code and path are shorter than message. If code and path come after message it's unlikely you'll ever see those columns. You can use Ctrlt to hide the picker preview to see the message column.

this makes sense only on larger screens. the "code" part is the least important part of the error message, and, as you can see, it covers most of the picker screen, even on my larger screen thinkpad and with smaller font. i, as a user, would rather press ctrl+t to get extra information (like some error code) rather than the opposite.

as you can see, error codes (at least for Haskell) are pretty long and not very descriptive and introduce extra visual noise.

fyi, on my older macbook, the situation is even worse, as the screen is smaller.
