Changes made

This pull request introduces several changes to enhance the functionality and robustness of the ProcessManager and related components in the engine. The most important changes include adding new service dependencies to ProcessManager, handling model validation in PythonEngine, and improving the handling of file paths in utility functions.

Enhancements to ProcessManager:

• engine/controllers/process_manager.cc: Added logic to stop running models when the destroy method is called. This ensures that all models are properly stopped before the application quits.
• engine/controllers/process_manager.h: Added new dependencies (InferenceService and ModelService) and a constructor to initialize these services. [1] [2]

Model validation in PythonEngine:

• engine/extensions/python-engine/python_engine.cc: Added checks in HandleInference and HandleRouteRequest methods to validate if the specified model is loaded before proceeding. If the model is not loaded, an error response is returned. [1] [2]

Improved file path handling:

• engine/utils/curl_utils.cc: Modified the SimpleGetJsonRecursive function to use std::filesystem::path for safer and more consistent file path handling.

Other changes:

• engine/main.cc: Updated the instantiation of ProcessManager to include the new service dependencies.
• engine/services/model_service.cc: Simplified the setting of executable permissions by removing platform-specific code and using a unified approach.
