Universal class for managing configuration files with caching support.
This class provides a general solution to load, save, and manage configuration

The `init()` method initializes the configuration file path, while `load()` and `save()`
synchronize data between the file and internal memory structures.
Key Features:
- Caching to minimize I/O operations.
- Default values for missing or corrupted configuration files.
- Reusability across different projects and use cases.
The class is designed for central application configuration management, working closely
with `ThemeManager` to dynamically manage themes or other settings.

- Tight integration with `ConfigManager` for persistent storage of preferences.
The class is designed to apply themes consistently throughout the application,
