Searching for items in a Plex "Other Videos"/home-video library returned
nothing, while the same query worked in Plex Web. `/library/search` with
`searchTypes=movies,tv,music` skips libraries on the Personal Media agent;
they only answer to the `otherVideos` category.
Add `otherVideos` to the search request and treat personal-media rows
(`*.agents.none://` guids) as their own category when a saturated response
is supplemented, so a large movie library cannot starve home videos and
vice versa.
