Lazy-load book page "Lists" section

[jimchamp]

Closes #10653

Replaces initial book page "Lists" section with a loading indicator. Whenever a patron scroll withing 200px of the "Lists" section, a /partials request is made for the section's content and the view is updated with the results.

If either the work or edition is on a list, the "See All" link becomes visible. This link was previously conditionally rendered, but is now always rendered with the hidden class.

I moved this conditional such that it wraps the entire "Lists" section div. This was done to avoid rendering an entirely empty lists section on "fake record" pages (as seen below):

The border of the "Lists" section is present when the if statement is nested within the div

Tested on testing, and lgtm! List correctly load on https://testing.openlibrary.org/books/OL1285376M/Les_mise%CC%81rables
