release search links from preservation summary tables

[bnewbold]

Currently the container preservation dashboards and general coverage search interface are useful for finding out that there are works lacking preservation. But it requires an extra regular release search to get the list of actual releases. For example, one ends up doing a lot of container-specific or general-purpose release queries with in_ia:false.

It would be helpful to instead just click a link from any preservation count table or maybe even bar chart to get to the same query.
