HoldingPen: GUI: Links to database

[ksachs]

Currently links to records in the database, e.g. match candidates point to labs.

When we use the HP in production, there should (also) be links to the production database, i.e. legacy.
Though the record information is the same, we might need to edit that record, which is only possible on the production database.

I would change the url of the links from
https://labs.inspirehep.net/literature/[recid]
to
https://inspirehep.net/record/[recid]

I hope that is only one place in the code.
