GET fleet/safety-events/audit-logs/feed: Adds uuid field to safetyEvent object

The GET fleet/safety-events/audit-logs/feed endpoint has some new features! Added an optional uuid field to the safetyEvent object in the response. This UUID is the unique Samsara ID for the safety event, matching the format used by the Safety Events Stream and Get Safety Events APIs. Use this field to correlate activity feed events with safety event data from those endpoints.
