Interface FacadeInterface.
The FacadeInterface defines the contract for all facade classes within the application.
It requires the implementation of the getFacadeAccessor method, which is crucial for
accessing the underlying instance from the application container. This allows facades
to provide a static interface to underlying services, making them easier to use
throughout the application.
Implementing this interface ensures that all facades follow a consistent pattern for resolving their underlying services, facilitating dependency injection and improving maintainability.
