Add ability to the user to filter lists by date added

[Evazisouli]

Closes #4267

Adding a new feature for sorting the Reading Log "Want to read" list of users by the date they have added their books.

Technical

Two filters added when being in the "Want to read" list, one for descending order and one for ascending.

Testing

1. Visit the Reading Log "Want to read" list
2. Two filters should appear, "Newest to Oldest" and "Oldest to Newest".
3. By clicking "Newest to Oldest" the books on the right should be sorted by the date the user has logged them in his list from newest logged to oldest logged.
4. By clicking "Oldest to Newest" the books on the right should be sorted by the date the user has logged them in his list from oldest logged to newest logged.

This looks great! This is going to be super useful :) A few code quality/UX feedback for you! Also, let's make the default going forward "Date added (newest)" instead of whatever random order the DB has these in :P

Thanks for the quick fixes! Looking good :) One small UX fix, and then it looks like there are also some code formatting issues: https://github.com/internetarchive/openlibrary/pull/5334/checks?check_run_id=2928114170#step:8:16 . These are mostly menial things, like adding new line characters. Once that's done, we should be good to merge!

Ah we'll also want to move this a little lower; just before the macros.Pages section:

Oh, this is also up on testing.openlibrary.org now, if you want to take it for a spin 👍

Lgtm! Tested on testing:

• Bar appears on all three types of shelves
• shelves now appear with most recent at top
• Switch sort order works
• Paging works when sort enabled

Context: I don't usually merge stuff on the weekends :P , but @Evazisouli and @STAMATIOSL have a course deadline on Monday that they're trying to meet. And they've been so friendly and polite and diligently followed all our community rules, and been patient and understanding while getting their environments up and running, and now created this wonderfully useful feature! So wanted to make sure they met their deadline :) Best of luck, @Evazisouli, @STAMATIOSL!
