Re-work legislation listing pages to support >10,000 works

[longhotsummer]

The big challenge here is that we load all the information into the page at once. That's no longer sustainable.

Proposal

TLDR; paginate the legislation listing pages like we do other listing pages, and bring the filtering and sorting functionality to all listing pages

1. change the legislation listing pages to be usual listing pages with pagination
2. implement filtering (not search) and sorting for all listing views using normal django forms (and perhaps htmx)
3. ensure that pocketlaw still works, or decide what needs to be disabled/hidden for pocketlaw (like filtering and sorting)

Things to ponder

• how do we adjust the listing page layout so the search box isn't confused with filter box?

done!
