Refactor: Add Lock for Thread-Safe Status Writing

[pyob-bot]

Summary of Changes

• Introduced a status_lock to ensure thread-safe access when updating the status_file.
• This change prevents potential race conditions by acquiring the lock before writing to the shared resource.

Technical Impact

• Thread Safety: By adding the status_lock, the code now safely handles concurrent writes to status_file. This is crucial in multi-threaded environments where data integrity must be maintained.
• Performance Considerations: Although thread locks can introduce some overhead, the impact is minimized by the lock's short scope within the function, ensuring only critical sections are protected against concurrent execution.
• Code Readability: The code's intention is clearer to developers who may interact with this file in the future, specifying the necessity of a lock for writing operations.

This refactoring enhances the stability and reliability of status updates in dashboard_server.py, contributing to a more robust application architecture.
