feat(trigger): enhance trigger plugin data structure and error handling

- Added `plugin_unique_identifier` to `PluginTriggerData` and `TriggerProviderApiEntity` to improve identification of trigger plugins.
- Introduced `PluginTriggerDispatchData` for structured dispatch data in Celery tasks, enhancing the clarity of trigger dispatching.
- Updated `dispatch_triggered_workflows_async` to utilize the new dispatch data structure, improving error handling and logging for trigger invocations.
- Enhanced metadata handling in `TriggerPluginNode` to include trigger information, aiding in debugging and tracking.

These changes improve the robustness and maintainability of trigger plugin interactions within the workflow system.
