Refactor useAuth hooks for improved type safety, error handling, and compliance with auto-generated API client

- Migrated `useAuth` hooks to use functions from auto-generated API client for improved maintainability and OpenAPI compliance.
- Replaced manual API calls with SDK functions (`login`, `register`, `logout`, etc.) and added error type guards for runtime safety (`isTokenWithUser`, `isSuccessResponse`).
- Enhanced hooks with better error logging, optional success callbacks, and stricter type annotations.
- Refactored `Logout` and `LogoutAll` mutations to handle missing tokens gracefully and clear local state on server failure.
- Added tests for API type guards and updated functionality of hooks to validate proper behaviors.
- Removed legacy `client-config.ts` to align with new API client utilization.
- Improved inline documentation for hooks with detailed descriptions and usage guidance.
