perf: drop includeSeries/includeMovie from history fetches

Sonarr/Radarr history with include* params forces expensive DB
joins (~2s each). History records still have seriesId/movieId
for matching; the series/movie objects come from the queue-built
maps instead.

Trade-off: completed downloads only show if the series/movie
is also currently in the queue. Active downloads unaffected.
