What problem would you like to solve? Please describe:
Currently, alerts, after being acknowledged, can remain open indefinitely if not manually closed. This leads to a backlog of forgotten alerts which can impact system processing and lead to confusion due to deduplication suppressing new alerts.

Describe the solution you'd like:
In the administration panel, under the maintenance settings, I'd like to add a boolean option that enables the "Alert Auto Close Days" setting to apply not only to unacknowledged alerts (current behavior) but also to acknowledged alerts. This would ensure all alerts are auto-closed after a certain period of inactivity, whether acknowledged or not.

Describe alternatives you've considered:
The only other alternative currently is to manually close out old alerts but this can be time-consuming and inefficient, especially on a larger scale.

Additional context:
Enabling this feature will alleviate system processing loads from old forgotten alerts, reduce confusion for users relating to new alerts being suppressed due to similar open alerts, and enhance alert management efficiency.
