refactor(trigger): Unify the Trigger Debug interface and event handling and enhance error management

- Updated `DraftWorkflowTriggerNodeApi` to utilize the new `TriggerDebugEvent` and `TriggerDebugEventPoller` for improved event polling.
- Removed deprecated `poll_debug_event` methods from `TriggerService`, `ScheduleService`, and `WebhookService`, consolidating functionality into the new event structure.
- Enhanced error handling in `invoke_trigger_event` to utilize `TriggerPluginInvokeError` for better clarity on invocation issues.
- Updated frontend API routes to reflect changes in trigger event handling, ensuring consistency across the application.
