[Feature]: Optional cleanup or archiving of removed media server users

[ReligusPotato78]

Describe the feature

It would be helpful to have an optional mechanism for handling users that have been removed from connected media servers (e.g., Jellyfin).

Currently, when users are deleted upstream, they remain visible in Tracearr after sync. While this may be intentional for historical tracking, it can result in outdated or unused accounts accumulating in the dashboard over time. This could be added as a configurable option as well with something like:

Option A: Automatically remove users that no longer exist on the media server
Option B: Mark them as inactive/archived instead of deleting
Option C: Keep current behavior (no removal) as default for backward compatibility

We do not delete data in Tracearr.

It's critical for historical data which is The Whole reason tracearr exists. And timecaleDB does not work well with deleting records or "archiving".

There are plenty of closed requests like this if more information is needed.
