Improved UI for filtering posts on score

Inspired by the confusion in https://meta.codidact.com/posts/290048 , I'd like to propose a UI enhancement. Using a spinner for this value doesn't make a lot of sense, since the user needs to think about what the value means, and that value is somewhat abstract. It takes considerable experience (or a full understanding plus some mental arithmetic skills) to translate "I want to see posts at +0/-2 or better" into "I want to see posts at a score >= .33" - and it's still a bit annoying at that point. Finally, it's annoying that the max score defaults to 0 and needs to be spun all the way up (aside from, I assume, a value of 0 being treated specially?).

I propose to replace the combo boxes for min score and max score filters with *sliders* - representing 0.00 on the left and 1.00 on the right, and defaulting to the extreme ends (showing that the default filter accepts the entire score range). This would echo the visual language of the rest of the site for displaying Wilson scores.

For bonus points:

* Render a heavy vertical line at the center point, like how the score indicators in the post listing view works

* Either show a shaded red->green background, or dynamically fill an appropriate part of the bar with either red or green as the slider is dragged

* Dynamically display example upvote/downvote tallies that would be accepted/rejected by the filter?
