feat(job): media availability support for jellyfin/emby (#522)

* 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 #406, fix #193, fix #516, fix #362, fix #84

* 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
