feat(trigger): enhance trigger event handling and introduce new debug event polling

- Refactored the `DraftWorkflowTriggerNodeApi` and related services to utilize the new `TriggerService` for polling debug events, improving modularity and clarity.
- Added `poll_debug_event` methods in `TriggerService`, `ScheduleService`, and `WebhookService` to streamline event handling for different trigger types.
- Introduced `ScheduleDebugEvent` and updated `PluginTriggerDebugEvent` to include a more structured approach for event data.
- Enhanced the `invoke_trigger_event` method to improve error handling and data validation during trigger invocations.
- Updated frontend API calls to align with the new event structure, removing deprecated parameters for cleaner integration.
