Watchlist and favorites sections keep their stored list order by default
(provider-synced positions first, then newest-added). An optional
sort/order config now supports title, release date, IMDb rating, and
date-added-to-list ordering, applied consistently on the home rail and
the catalog "see all" page. added_at is resolved from the list entries
via a shared OrderPersonalListIDs helper since it is distinct from the
catalog's library added_at. The section editor gains a Sort dropdown.
