Refactor request handling in BranchRequestQueue to improve failure management

- Updated the processRequest method to handle request failures instead of re-queuing, enhancing error handling logic.
- Simplified the logic for requests waiting on processes to finish by invoking handleFailure, improving clarity and maintainability.
- Ensured all changes align with existing functionality while improving the robustness of request processing.
