Pull Request Overview

This PR refactors the architecture of the datagrid widget's state management and dependency injection system, transitioning from a monolithic approach to a more modular, atom-based pattern using MobX computed values and event emitters.

Key Changes

• Atom-based state management: Introduces granular, composable atoms for datasource properties, selection state, and empty state management
• Event-driven select-all feature: Refactors SelectAllService and SelectAllBarViewModel to use an event emitter pattern instead of direct method calls
• Dependency injection reorganization: Splits tokens into CORE_TOKENS, DG_TOKENS, and SA_TOKENS for better separation of concerns
• Bug fix: Corrects clearInterval to clearTimeout in DatasourceService
