Explore progressive enhancement of /all for a11y

[robhudson]

One-line summary

This is an exploration in using progressive enhancement to load only the changed content to improve the a11y issues brought up in the Github issue.

This is an htmx-like approach to rendering only the partial HTML content rather than the full page and using innerHTML to write the partial content in place. This seems to work well for me locally but I'm not sure if this solves the a11y issues.

• I used an AI to write some of this code.

Significant changes and points to review

I'm interested if these changes help alleviate this specific issue:

However, when a user selects an item, the page reloads and doesn't automatically take a screen reader user to the next selection, forcing them to go through the page from the beginning.

@reemhamz Would you be willing to look at this locally with your screen reader to see if it helps at all?

Just tested it, and unfortunately it's still disrupting the user flow as it was prior :/ were you able to test it using a screenreader? If so, did it produce different results on your end?
