Refactor Summaries

[Smullz622]

When ILLiad goes down, it breaks the summaries page as that page makes synchronous calls to get IlliadResponse. We have a temporary fix out where we don't raise an error, allowing the page to still render (PR here), but this is not an ideal permanent solution.

Ideal solution would be to refactor to use async calls similar to holds/checkouts. Instead of all the logic currently in app/view/summaries/_summary.html.erb, we would have a summaries job that handles all the summary data & returns a partial of the summaries table.
