test: enhance text generation and workflow callbacks tests

- Added comprehensive tests for the useTextGeneration hook, covering handleSend and handleStop functionalities, including file processing and error handling.
- Improved workflow callbacks tests to handle edge cases and ensure graceful handling of missing nodes and undefined tracing.
- Introduced new test cases for validating prompt variables and processing files in the text generation flow.
