fix(feed): use versionToTimeFeedGenerator for authenticated TIME feed

The authenticated TIME feed should use exactly the same config as
POPULARITY feed (versionToFeedGenerator), with only order_by: date
added. This ensures consistent behavior between anonymous and
authenticated feeds, using the proper Lofn config generator.
