Suggest additional author IDs based on existing IDs

If an author has a Wikidata or VIAF id stored, then it's possible to retrieve a bunch of other IDs from viaf.org or wikidata.org as JSON.

These could be presented to a user while editing an author, to allow them to easily check and add them.

### Proposal & Constraints
I've build a prototype of this, here's a video of the general workflow:

This, once visually tidied up, seems like a minimally viable use, but it could be expanded further. The information coming from Wikidata could be expanded to author photos, birthdate etc. suggestions.

Special handling could be added for when the three sources disagree, flagging up issues to the editor. And rather than being opt-in, perhaps some librarians could have this run automatically in the background when editing to flag issues.

It could also probably be used in a very similar form for IDs on Edition pages e.g. the Wikidata and OpenLibrary entries for this edition have overlapping but not identical IDs from the list OpenLibrary support, but it's currently a bit of a chore to check and add these:
