add automated DOI registration

What's Changed

Published, peer reviewed models in the Model Library will now automatically receive a DOI from DataCite. Currently happening on a nightly, batched basis but should transition into an async action via huey when #718 is merged.

Also includes an upgrade to postgres 16 that will require production data migration and brief downtime.
