feat: Add command enable/disable configuration for various commands

- Implemented a configuration option for enabling or disabling commands across multiple command classes.
- Each command now checks its enabled state before execution, improving control over command availability.
- Updated the configuration loading mechanism to retrieve the enabled state from the config file for commands like Advert, AQI, Catfact, and others.
