feat(trigger): implement trigger debugging functionality

- Added DraftWorkflowTriggerNodeApi and DraftWorkflowTriggerRunApi for debugging trigger nodes and workflows.
- Enhanced TriggerDebugService to manage trigger debugging sessions and event listening.
- Introduced structured event responses for trigger debugging, including listening started, received, node finished, and workflow started events.
- Updated Queue and Stream entities to support new trigger debug events.
- Refactored trigger input handling to streamline the process of creating inputs from trigger data.

This implementation improves the debugging capabilities for trigger nodes and workflows, providing clearer event handling and structured responses.
