Pull Request Overview

This is a work-in-progress pull request that performs a major architectural refactoring of the Data Grid widget, introducing dependency injection patterns, modernizing state management with MobX, and upgrading the React Testing Library. The changes improve code organization, testability, and maintainability while preserving existing functionality.

Key Changes:

• Upgraded @testing-library/react from 13.4.0 to 16.3.0
• Introduced dependency injection using Brandi containers with organized token namespaces (CORE_TOKENS, DG_TOKENS, SA_TOKENS)
• Refactored selection logic into service interfaces (SelectionHelperService, SelectActionsService) with factory functions
• Simplified React components by removing prop drilling and using injection hooks
• Rewrote tests to use atomic state patterns instead of GateProvider patterns
