Audit Log Event refactor

[cikzh]

Refactors the Audit Events

• AuditEvent enum is renamed to AuditEventType and is now a flat enum
• AsAuditEvent trait added, so we can move implementation details away from audit_log module
• existing event_name database column is used for saving and returning the AuditEventType to the frontend. A rename of the column might be appropriate
