Idle Users Cleanup

<p>Automatically free up seats in KNIME Business Hub by removing users who are inactive.</p><p>This data app identifies inactive users based on two criteria: <strong>they have not logged in for the configured number of days</strong> and <strong>they have no active deployments in their user scope</strong>. Once detected, the workflow removes these users from all Hub teams they belong to, freeing up seats.</p><p>Optionally, administrators can be notified via email after removal by configuring the “Notify User” component.</p><p>The data app requires access to Keycloak session events to track user activity. Therefore, the Keycloak service client credentials (Client ID and Client Secret) must be provided.</p>
