Create edition de-conflation UI

Sometimes books get conflated, for example as part of a series. If this affects only two works and a dozen editions, the current UI works fine. But if one has to juggle large series or many reprints, it strains my coordination.

### Describe the problem that you'd like solved

I want an interface where I can input books, which are then listed with their editions. The editions can be filtered and moved from one work to the other. Once it was correctly sorted, one can click on "apply" and write the changes into the database.

Ideally, I could select works from a search result and click a "De-Conflate Editions" button.

### Proposal & Constraints

Most functions should already exists, one can drag and drop editions from one work to the other. It is just a little tedious if it involves many open tabs.

I build my mock-up with a HTML kanban board tool.
