Refactor Spark app route and simplify notebook path handling

- Removed unused JWT and user identification decorators from the Spark app route in spark_app.py for cleaner code.
- Simplified the notebook path handling in getSparkApps method of NotebookModel.js by removing unnecessary path simplification logic, allowing direct usage of the provided notebook path.
- Enhanced code readability and maintainability by streamlining the logic in both files.
