refactor(trigger): unify debug event handling and improve polling mechanism

- Introduced a base class for debug events to streamline event handling.
- Refactored `TriggerDebugService` to support multiple event types through a generic dispatch/poll interface.
- Updated webhook and plugin trigger debug services to utilize the new event structure.
- Enhanced the dispatch logic in `dispatch_triggered_workflows_async` to accommodate the new event model.
