feat: add group event history

Description

This PR introduces group event history for relevant actors.

• Who: admins and group owners.
• What: group-related IAM events.

I took inspiration from what was already done for password-related events.

Remarks:

• Not all IAM events are group-related.
  IAM events don't all have group_id info, as it is stored in an unstructured way. Hence, event filtering is a 2 step process: first filter on SQL request, then on unstructured data using plain Python. This should be OK as a first approach as the volume of such events is likely to be limited.
• Non-admin group owners cannot see their group's users.
  This yielded an issue when attempting to use the 'isOwner' prop to control the display of the button opening the History modal.
