fix(fastapi): utilize auto_{orphan,deletion}_age

Didn't get this in when the initial request port went down; here it is.

Auto-accept orphan requests when the package has been out of date for longer than auto_orphan_age.

Auto-accept deletion requests by the package's maintainer if the package has been uploaded within auto_deletion_age seconds ago.
