Audit trail

Wagtail comes with page revision history, which is a great tool. However, it would be nice to have a full centralized audit trail of all user actions performed on the site. This would include login, password change, settings save, page publishes, etc.

The audit trail would likely be its own simple normalized data structure for each audit event that occurs, with option to export to CSV.

Start by reviewing Wagtail's existing page revision history and the site actions named in the issue, including login, password changes, settings saves, and page publishing. Define what events must be recorded, how the normalized audit structure should work, and what CSV export must include before implementation can be considered done.
