Direct ORCID links

https://aclanthology.org/people/0000-0002-1297-6794 should redirect to https://aclanthology.org/people/matt-post/

Start by tracing how the /people/ URL entry point handles identifiers, using the ORCID URL and Matt Post URL in the issue as the expected case. Confirm that the ORCID URL redirects to the named person page, and check the relevant existing route or redirect tests if present. The issue is assigned, so confirm availability before starting.
