Pull Request Overview

This PR fixes broken sync actions by adding an exception handler that captures and returns tracebacks in the JSON response, and applies a broad code-style cleanup across the repository.

• Added sync_action_exception_handler decorator to wrap all @sync_action methods, catching unhandled exceptions and returning a structured traceback.
• Standardized all string literals to double quotes and ensured trailing commas in multi-line literals for consistency.
• Reformatted dict and argument formatting in tests and source files for readability.
