The jellyfinMediaId(4k) properties were inferred as string | undefined, causing them to be set to
undefined when assigning null. This prevented the media from being saved correctly to the SQLite
database, as it doesn't accept undefined values. This resolves the availabilitySync job issue where
the "play on" button wasn't being removed for all media server types.
fix#668
Previously `jellyfinMediaId4k` was being assigned even if 4k server was not setup or even if 4k
content were not present. This fixes it by conditionally assigning the jellyfinMediaId and
JellyfinMediaId4k
fix#681
* feat(job): media availability support for jellyfin/emby
This refactors the media availability job to support jellyfin/emby for media removal automatically.
Needs further testing on 4k items (as I have not yet tested with 4k), however, non-4k items work as
intended.

* fix(availabilitysync): use the correct 4k jellyfinMediaId
* fix: season mapping for plex
Fixes a bug introduced with this PR where media availability sync job removed the seasons from all
series even when those seasons existed
