Pull request overview
This pull request fixes a critical bug where the availability sync incorrectly marks TV seasons as deleted when the media server (Plex/Jellyfin/Emby) becomes temporarily unreachable, even though the media still exists in Sonarr. The fix restores proper fail-safe behavior and corrects the map merging logic to prioritize data sources correctly.
Changes:
- Simplified and corrected the season map merging logic to use spread operator syntax, ensuring proper priority order (filtered → media server → Sonarr)
- Fixed Jellyfin error handling logic to correctly detect non-404/non-500 errors and fail-safe by assuming media exists when the server is unreachable

Description
Fixes an issue where media availability sync would incorrectly mark seasons as deleted when the media server (Plex/Jellyfin/Emby) is temporarily unreachable, even when the media still exists in Sonarr. The bug was caused by faulty season map merging logic that prevented Sonarr's results from overriding the initial "not found" state, combined with incorrect error handling in the Jellyfin implementation. This caused the watchlist sync to recreate requests for already-available media when the media server went offline. The fix restores the original Overseerr map merging behavior and corrects Jellyfin's error handling to fail-safe when the server is unreachable.
