fix: read episodeNumber from nested episode object in Sonarr records

Sonarr queue and history records do not expose episodeNumber at the
top level — it is only present inside the nested episode object
(record.episode.episodeNumber). Same for seasonNumber. The original
extractEpisode() read record.episodeNumber which was always undefined,
so gatherEpisodes() always returned an empty array.

Fix: prefer the nested episode object fields, falling back to the
top-level fields for forward-compatibility.
