feat: add setting to set the max number of articles per page

[patrickkempff]

This PR introduces a new article_limit setting so you can control how many articles to fetch/display on the home and topic pages from the setting page. By default it remains at 8 (preserving prior behavior), but you can now bump it up (e.g. to 16) or lower it to suit your needs.

Background

• The previous implementation hard-coded a limit of 8 articles.
• I often find 16 articles more useful for my liking, so rather than keep hacking the source, this makes it configurable.

Thanks!
Currently I'm having some issues with my cache and don't want to add more settings until I have it fixed.

Totally understand 👍 But would it be possible to merge this and release a new Docker tag? That way you can keep using your current version while others can enjoy this new setting as well :-) Thanks!

@HookedBehemoth any updates on when this will be merged?
