Bug: Invalid Events Trigger Failing Actions

Removing the detector existence check allows workflow fire histories to be created and actions to be triggered for events without detectors. Previously, events missing detectors were skipped with a warning. Now, trigger_action tasks will be queued and fail when get_detector_by_event raises Detector.DoesNotExist, causing unnecessary task failures and retries instead of gracefully handling missing detectors upfront.
