Avoid redundant Audit log entries

[DavidePrincipi]

The Audit log page currently records many events of type context-task and status-task, which do not include any useful information. These redundant entries unnecessarily increase the size of the SQLite database and impact the performance of the API server, especially on slower systems. To address this, these events should no longer be logged.

In Testing core 3.13.0-dev.3

Test case

For new and updated installations, check that in Audit Trail page only login-ok and create-task events are recorded.
