More visible selected article (#8230)

There was not enough difference between selected and not-selected articles, especially not due to hovering using the same style.
Already relevant as is, and more relevant for a future feature depending on selected article.
Additional help welcome to further improve the styling, in this PR or a future one, also for the other themes.

In this example, the third article is the one selected:

<img width="443" height="189" alt="image" src="https://github.com/user-attachments/assets/06168e9f-1b91-47e2-9b64-4fd8ca6c7186" />

* Compensate the increased border-left-width

* Implement in Pafat

* Implement in Nord

* Shorten comment

* Implement in Alternative Dark

* Implement for Flat

* Implement for Swage

* Implement in Ansum and Mapco

* Call stylelint_fix before rtlcss
So that RTLCSS includes the fixes from previous step
