This commit removes a handful of magic numbers and instead relies on a
constant.
This has a small impact in that the Basic feed will now return 50
articles instead of 25. However, normalizing the feed pagination window
size helps reduce some oddities in reporting.
In addition, this might be something we consider giving administrators
the ability to set (with default options, because we shouldn't allow
page sizes of 10_000 as that's a massive memory hog).

This is a hypothetical and experimental interface change. The goal of
the change is to begin looking at what a "Feed"'s method interface would
look like.
I would like to reduce the controller logic necessary for deciding on
different strategies, and instead defer to a builder/strategy lookup
pattern.
Prior to this commit, there existed duplicate logic between two of the
primary user feeds. This refactor introduces a new object which is
solely concerned with calculating scores to add to an article base score.
With this commit, we can introduce A/B testing by changing passing
different config values to `ArticleScoreCalculatorForUser.new`.
My suspicion is that for some of this, we might be able to better
leverage the database via select statements and SQL sums. However, that
is presently outside of what I'm prepared to tackle.
