Paginator component grows out of bounds

### What went wrong?

On the search results page, the row that contains the sort dropdown and the paginator can become wider than its container. Looks weird, see screenshots below.

### What did you expect to happen?

In these screenshots, you can see that there is a significant margin on the left of the row, so this could probably be spaced out better. But if it all doesn't fit, it might be better to spread the controls over two rows?

Btw, we're already aware that spacing/layout in this section is just kind of bad in general (lots of empty space etc), so this issue will probably be combined with a larger update in this section.

### Screenshot

Looks worse in the sticky view when you scroll down:

### Version

5.26.0

### Steps to reproduce

- Go to https://textcavator.hum.uu.nl/search/dbnl?sort=year,asc&p=4

Start by reproducing the layout at https://textcavator.hum.uu.nl/search/dbnl?sort=year,asc&p=4, including the sticky view after scrolling. Identify the search-results row containing the sort dropdown and paginator; done means the controls remain within their container and use an acceptable layout when they do not fit.
