Domain Layer - use cases - business rules setup

Core: Domain Layer

Support Reactive Navigation: Utilize the Domain Layer as the catalyst for routing. Use Cases drive session state changes in SessionManager, which MainActivity observes to perform reactive Compose Navigation transitions.

[NEW] Result.kt

• Standardized success/failure wrapper for Use Cases.

[NEW] BaseUseCase.kt

• Represents a single business transaction or user action.

[NEW] LoginUseCase.kt - Atomic Business Transaction:

• Validate input using the Credentials domain model.
• Execute authentication via the Data layer.
• Apply Domain transformations (e.g., name formatting).
• Commit the session state to the Single Source of Truth (SessionManager).

[NEW] LogoutUseCase.kt

• Atomic termination of user session, triggering the reactive navigation flow.
